How to measure the temperature of a room?

Whether in winter or summer, the temperature of the room where you sleep is essential to have a good night's sleep. And is that, if it is too high or too low, not sleeping well will affect the day to day physically and mentally.

That is why it is essential to find a way to measure the temperature of the rooms, even the whole house. And it is that depending on how your home is, you will have felt that in some rooms it is better than in others. So, with the right tool, you may even consider sleeping in another room.

Having controlled not only the temperature, but also the humidity of your home, facilitates the prevention of diseases and the appearance of mold. The combination of both can make your furniture age faster, even if you have respiratory problems.

So what is the best method to measure the temperature of a room? And of the whole house? Already on, why not from the garden?

Weather stations: the best solution

Weather stations are the ideal solution to have an easy and simple control of the temperature and humidity of your home. With them you can have a comfortable and precise tool without the need to invest too much or put mercury thermometers in all your rooms

But not only that, but thanks to technological advances you can find weather stations that can measure the barometric pressure, the direction and strength of the wind and even UV rays. These digital tools also offer you forecasts with more or less success, depending on the data collected.

And for that you don't need to have a hulk with a lot of measuring gadgets. With just a small station that fits in both hands you have more than enough.

In general, weather stations are made up of a central station and one or more remote sensors, allowing you to know all the information about the house with a simple glance at your screen. Or even from your mobile, if you have one of the fantastic featured models of Wi-Fi weather stations.

By installing a compatible app, you will be able to know what the weather is like at home from the comfort of your work; know how the room where your children sleep is located and know the most comfortable place when temperatures rise or fall too low.

How to choose the right model?

You will find a great variety of models of weather stations. From very simple stations that collect basic information to some much more complex that will need an installation in conditions outside. If you are interested in acquiring a weather station, we recommend that you take a look at this website , as they offer different buying guides that will be very useful.

In short, the fundamental thing is that the station you choose is capable of transmitting the ambient data comfortably, that is, via mobile. And for this the best are the wi-fi weather stations. If you are looking to buy a bluetooth or wi-fi weather station, one of the most interesting and complete is the one offered by Netatmo. Its design is elegant, with an interior sensor and an exterior sensor, it has great connectivity and you can check everything through your mobile. It will undoubtedly be a tool that will change your life.

The mobile battery allows you to know the indoor temperature in real time

Modern smartphones have a sensor that measures the temperature of the phone's lithium battery to prevent it from overheating, which can be dangerous.

The increase in battery temperature can be due to environmental conditions, intensive use of the phone, or it can increase in areas with less coverage, where the processor constantly works to search for the signal and maintain the connection with the mobile network.

In fact, it is not strange that a phone goes into low power mode - for example, lowering the brightness of the screen or reducing its performance - when they detect an increase in its temperature.

Correlation between ambient and mobile temperature

Taking advantage of this data, Dutch researchers are determining how to measure the ambient temperature from the temperature of the mobile . Both data are not similar, since the temperature of the battery of a phone even at rest is somewhat higher than the ambient temperature.

However, the researchers have managed to determine a strong correlation between the ambient temperature and the temperature of the mobile battery when a sufficient amount of this data is processed, when it is obtained from a large enough user base.

To develop the calculation algorithm, the researchers obtained the battery temperature data from the information sent by thousands of phones that make use of the OpenSignal application , a collaborative service that determines the presence and intensity of battery signals. wifi and mobile phone worldwide and shows data on local coverage maps.

It is estimated that the applicationOpenSignal captures up to a million of these readings every day from about 150,000 Android phones, although at the moment the researchers are working with measurements from only a dozen cities.

Know the temperature accurately

Measuring the temperature in a distributed way in the interior of cities offers more reliable data that is also constantly updated , almost in real time and unlike what happens if only the data obtained by fixed weather stations are considered.

These have a much smaller number and in most cases outside the city centers whose data is also updated much less frequently.

"Knowing precisely the temperature of the city is especially important due to the 'island effect' produced by urban heat. Basically the center of a city tends to be warmer than its surroundings due to the presence of materials that absorb heat such as asphalt, cement and buildings, among other things this represents an increased risk - even death - for a part of the population, especially among the very young and the elderly, "they explain in Inside Science .

To determine the correct relationship,the algorithm must consider the heat transfer from the user's body to the phone and the ambient temperature , especially in summer.

It even varies from one phone to another depending on its construction -material and insulating capacity- and efficiency -the heat dissipated during its operation. The system must also consider the seasons of the year, and in theory it must also distinguish when a telephone is outside or inside and if it is day or night.

However, according to the researchers, when buying the data obtained with their algorithm and the real measurements abroad - obtained from the information provided by the airports in these cities - they observed that, in the worst case, the variation was barely 1.5 degree, which has merit considering that differences between battery temperature and 'real' ambient temperature can multiply that difference tenfold .
