Temperature sensors
Temperature measurement is an elementary activity while monitoring the operation of a device or a robot. Measuring temperature is necessary in many processes, including production ones, which is why specialized sensors for measuring temperature are in demand on the production equipment market. In addition, temperature sensors - in less advanced, but very practical versions - are also important devices in our homes, because they greatly affect our perceptible comfort in a given room. Without a temperature sensor, you cannot create many interesting Internet of Things projects. If you are looking for a solution that will allow you to build your own air heating / cooling system, it goes without saying that you need to equip yourself with a temperature sensor!

Temperature sensors - FAQ
A thermistor is a type of resistor that works slightly differently than its "ordinary" brother - it changes resistance (resistance) in response to a change in temperature. Most often, the thermistor is semiconductor or metal. You will find them in engines, microwaves and thermostats.
Thermistors are used as temperature sensors . They can be found in everyday appliances such as fire alarms, ovens and refrigerators. They are also used in digital thermometers and in many automotive applications to measure temperature.
After heating the thermistor, its resistance should begin to decrease systematically within a few seconds of heating. If the NTC thermistor behaves the same, it is good. If not, it is damaged and should be thrown away.
