How to measure temperature without a thermometer in a room

In addition to basic tasks, smartphones have many additional capabilities.

A good example is using your phone as a thermometer. The Android operating system does not have this built-in capability, but independent developers have created many apps that can approximate room temperature. Most of these programs are completely free.

It is important to note that the accuracy of such measurements is low. This is due to the use of a temperature sensor designed to detect overheating of the built-in components, rather than the environment.

Temperature Applications

Let's look at several popular temperature measurement applications that can be downloaded from Google Play.

Heaven Thermo . An application that allows you to turn almost any smartphone into a thermometer. After startup, it is recommended to use the “Calibration” section, designed to improve the accuracy of readings. The utility has a beautiful interface - the results are visualized in the form of a mercury thermometer column, and below are the digital measurement results. The accuracy is approximately 5 degrees.

Simple Thermometer . The program has a simple interface. Immediately after startup, the ambient temperature is displayed in Celsius and Fahrenheit. An important advantage is its small size - the program is lightweight and practically does not consume RAM. According to user reviews, the discrepancy in readings reaches 4-7 degrees compared to an ordinary thermometer.

Maxzieli Thermometer (Environmental Thermometer). A simple mobile thermometer showing the ambient temperature in the form of a pie chart. After launching the application, the measurement results are immediately displayed on the screen. Depending on the temperature, the color of the scale changes from blue to red. Reviews say that the accuracy of the results ranges from 3 to 5 degrees.

How to determine the temperature without a thermometer in an adult or child?

To determine the presence of fever, it is useless to touch the arms and legs. Because they can be absolutely cold. This happens in children.

Methods:

• The places that most accurately tell you about an increase in temperature are the forehead, neck, armpits, under the knees, and also the tummy in children. It is these places that should be touched in order to determine the presence of fever.
• Touch what you need with your hands. For greater accuracy, you need to touch the hot area with your lips
• Children's eyelids can be touched. Place your lips on your baby's forehead and feel. Usually a temperature rise above 37.5 degrees is felt
• Signs of high fever are nausea and vomiting. There is weakness and lethargy
• The most interesting thing is that many children, even at a temperature above 38 degrees, can run around and be quite cheerful, but at the same time other symptoms of fever remain
• Pay attention to the color of your child's urine. The fact is that when the temperature rises, adults usually drink large amounts of water, which dries them out. Young children may not ask for liquids. Therefore, you need to give your child something to drink from time to time.
• Look at the color of his urine. As the temperature rises, the body becomes dehydrated and moisture evaporates quickly. In this case, the color of the urine becomes bright yellow, even orange. If this occurs in your child, it indicates a fever.
• One of the most dangerous symptoms of fever is seizures. In children under 5 years of age, convulsions often occur when the temperature rises to 39 degrees. If they last no more than 3 minutes, then there is nothing to worry about. But usually the parents of such children have antipyretic and special anticonvulsant drugs in their medicine cabinet. They must be given to the child because it can be dangerous.
• If you have seizures that last more than 3 minutes, you must urgently call an ambulance, because the phenomenon is neurologically dangerous. This may affect brain function

Child's temperature

Touching the forehead

This simple method is known to almost everyone, because it is actively used by mothers and grandmothers to quickly determine the child’s condition. The fact is that the temperature of a healthy sick person is different and it is difficult not to feel this difference.

As the temperature rises, a person's forehead becomes hot, but this symptom should be used as a reliable indicator. The fact is that the skin can cool under the influence of perspiration, thereby providing false information.

More reliable ideas about a person’s condition can be obtained by touching the skin in the neck, under the arms or on the stomach.

If you feel hot skin when touched, we are most likely talking about exceeding the temperature mark of 38 degrees. It is quite difficult to detect temperatures below 38 degrees in this way. If at the same time there is coldness in the fingers and toes, then we are talking about extreme heat.

Breath

Confused, rapid and intense breathing may indicate a high temperature. Normally, you can inhale and exhale about 17 times per minute, but in hot weather the frequency increases up to 25 times.

Pulse

The norm is 60-80 beats per minute, and if the fever is strong, the heart beats faster. Each degree adds about ten beats, it turns out that at a temperature of 38 degrees the heart beats approximately 90-100 times per minute.

Other signs

There are situations when, without measurements, it is clear that the patient is suffering from high fever. You can immediately determine that there is a temperature without a thermometer: a person has a fever, delirium appears, and convulsions develop. In this case, it is necessary to urgently call an ambulance, as this condition is extremely dangerous.

Some people may feel hot all over their body, and this is due to certain changes in the body, but the temperature will be normal. The condition of the legs and arms is not an indicator; even in extreme heat they can be cold.

You need to monitor children especially carefully, as they cannot always voice and explain that they feel bad. If lethargy and drowsiness appear, and the child refuses to eat, then you should pay attention to this.

In an adult, a high temperature may be accompanied by a headache, and the color of the urine becomes bright, which indicates dehydration. The patient alternates between feeling hot and cold. If other family members do not experience discomfort and cold in the same room as a potential patient, then only the one experiencing chills has a fever.

Temperature measurement accuracy

Since an integrated sensor is used to measure temperature, the applications discussed are not very accurate. For plausible testimony, it is recommended to adhere to several rules.

1. It is necessary to run pre-calibration if such an option is available in the application.
2. Before starting the program, the phone must be idle (at least 10 minutes) to allow the internal components to cool down. If the mobile device was charging or was in the hands of the owner for a long time, the measurements will be erroneous.

How to determine the presence of fever without a thermometer: signs of high temperature

Of course, it is difficult to determine heat with high accuracy without measuring equipment. The average person feels a temperature above 38 degrees, so if the patient has a slight increase, you are unlikely to detect it. Only a thermometer can do this. But if a person has a strong fever that needs to be brought down, it is quite noticeable.

Signs of fever:

• Rapid breathing. It is quite heavy, intermittent
• Rapid pulse. Typically, people with a fever have beats per minute greater than 100
• The appearance of an unhealthy blush. It is difficult to notice if a person has dark skin. Usually seen on people with fair skin
• A person may experience short-term convulsions. This usually happens when the temperature rises to 39 degrees.
• During a fever, the skin may be sticky and wet.
• A person is constantly thirsty and feels dry
• Chills may occur. Despite the fact that the room temperature is comfortable, the patient is shaking and constantly wants to cover himself with a warm blanket or put on a large amount of clothing
• Cold extremities. This often happens in children with cold fever.

Symptoms of high fever

Children react especially sharply to infection, and their health deteriorates rapidly. Here the child was just running around and having fun, and then he immediately becomes lethargic and capricious. When body temperature rises, the following appears:

• weakness;
• fever and chills;
• joint pain;
• nausea;
• convulsions;
• thirst;
• confusion;
• eyes water;
• the color of the skin changes, the face and body become red or covered with spots.

But you shouldn’t rely only on these signs, since each person is individual, and symptoms can manifest themselves in different ways. It’s better to use a thermometer, then it’s clear what to do next.

It is impossible to tolerate a high temperature for a long time, as dehydration occurs and the person gets worse. After the doctor examines the patient and prescribes medications, it is necessary to monitor the indications and monitor the patient.

Results

The built-in temperature sensor in the phone is not capable of providing accurate measurement results - the readings will vary between 3-7 degrees Celsius. If you follow the instructions, you can achieve an accuracy of up to 3 degrees. To do this, you need to perform calibration and not use the smartphone for some time before starting measurements, so that the components of the gadget do not heat up.

There is not always a thermometer at hand to measure the ambient temperature (in the room, outside). On the Internet you can find information that measurements can be carried out using a phone - in the interface of a special application. Is it so? In what cases is measurement possible?

How to correctly draw up a measurement report?

First of all, violations of heat supply parameters should be reported to the emergency dispatch service (ADS). An oral or written application is subject to mandatory registration.

The dispatcher can explain the situation if suddenly an accident occurs on the heating main. When a service employee does not have information about the cause of a heat supply failure, he is obliged to send an emergency team to find out the reasons and draw up a measurement report, having agreed on the time and date with the consumer.

The temperature must be measured with an accurate device that has all the necessary documents. The act contains information such as:

• Date and time of compilation;
• Characteristics of the apartment (address, area, number of floors, number of rooms);
• Composition of the commission, including the consumer;
• Meter data;
• Temperature settings;
• Signatures of all commission members.

One copy of the act remains at the disposal of the service provider, the second - with the customer.

An important fact: the homeowner’s disagreement with the conclusions of housing and communal services employees must be reflected in the act and a new commission must be appointed with the involvement of employees of Rospotrebnadzor or the State Housing Inspectorate.

In addition to the fact that utility companies must recalculate for violation of obligations, the contract for the supply of services, as a rule, contains a clause on the collection of penalties from the contractor for poor-quality heat supply.

Is it possible to measure the temperature in a room using a phone?

The phone can have two built-in sensors for measuring temperature - external and internal. The latter is used to diagnose the temperature inside the device - its components. This helps to avoid overheating of the smartphone and its damage.

Not all phone models have a sensor for measuring external (ambient) temperature. They are definitely present in the following smartphones: Runbo X5, Samsung Galaxy S4, Samsung Note 3, Snopow M6, Casio g'zone commando 4G.

If your phone is not on this list, most likely you do not have a sensor to measure external temperature - you will not be able to determine it, even if you download a special thermometer in the Play Market. In this case, we still recommend using a regular thermometer to find out the exact value. If you are in doubt whether you have a sensor or not, look at the technical specifications of your phone.

Samsung Galaxy S4 has a built-in adapter for detecting ambient temperature

How to measure the temperature in a room using a smartphone

If your smartphone has a sensor for measuring ambient temperature, most likely, its system already has a pre-installed program for measuring it. In Samsung, for example, this option is performed by the S Health application. It takes many measurements that are needed to determine the current state of the body: pulse, number of calories eaten, hours of sleep, number of kilometers traveled, as well as ambient temperature - because our general well-being also depends on it.

What to do in case of high temperature?

In children, an increase in temperature is often accompanied by convulsions, so you should carefully monitor the baby’s condition so that you can promptly seek qualified help.

It is recommended to call an ambulance if the duration of the convulsions is three minutes or more, as well as in the situation if this symptom is accompanied by vomiting, stiff neck, breathing problems and severe drowsiness.

Qualified help should not be ignored even if we are talking about a sick child under the age of 2 years, as well as if disturbing symptoms persist for 24 hours or more.

Calling an ambulance is strongly recommended even when an increase in temperature is accompanied by severe pain in the abdomen, chest, confusion or hallucinations.

To normalize the condition, you can use medications designed to reduce temperature indicators. It is also important to drink as much fluid as possible, ensure regular and nutritious meals, and give preference to bed rest so that the body has the opportunity to recover faster.
