The role of the temperature and humidity sensor is of course to sense the temperature and humidity in the current environment, and then transfer the temperature and humidity parameters to the transit system through the unique transmission methods of each system. The transit system transmits the data to the user interface after processing the data, and the user can clearly Read the current temperature and humidity information, and control it to make corresponding actions.
Temperature and humidity sensors are used in many industries, such as agriculture, forestry, animal husbandry, food transportation, file management, building materials management, laboratory management, construction, medical and health industries, museum monitoring, and many other industry categories.
The common application of temperature and humidity sensors is the air-conditioning temperature and humidity control system commonly used in our homes. We can set the desired temperature through the remote control. After the air conditioner is turned on, it will enable the temperature and humidity sensor terminal to measure the temperature of the current environment. The current temperature value is displayed on the display panel, and then the current temperature value is compared with the temperature value set by the user. If the current temperature is greater than the set temperature, the cooling device is started to perform the cooling process; if the temperature is lower than the set temperature, the heating device is started Warming treatment. The measurement and control of humidity and temperature are a principle.
In other words, in general systems with temperature and humidity sensors , the applications of temperature and humidity sensors are very similar. Just according to different industries, the range and accuracy of temperature and humidity sensors required are different.
Temperature and humidity sensors are so widely used, so how should we take care of them?
1. Clean the case. If the sensor case is dirty, you should use a clean, moist cloth to remove foreign objects. Do not use cleaning materials that are corrosive.
2. Power off when not needed.
3. In the harsh and changeable areas, attention should be paid to the protection of the chip inside the temperature and humidity sensor.
4. Do not exceed the range of the sensor in use. What kind of sensors measure what kind of environmental parameters.
