The high-precision humidity measurement sensor module is used on the air conditioning control panel to detect the indoor environment temperature and humidity

With the continuous development of society nowadays, people’s living standards are constantly improving, and the quality of life is getting better and better. Now almost every family has air conditioners installed. The appearance of air conditioners has brought great convenience to our lives. , It is very convenient to use. There is a control panel in the air conditioner, and the air conditioner works through the control panel. The air conditioner control panel is a panel that the user indirectly controls the air conditioner operating mechanism to realize various functions of the air conditioner. For example, there are function selection keys, temperature keys, air adjustment keys, and rear window defrost keys on the car air conditioner control panel.

The principle of air conditioning control panel:
1. The most basic principle of air conditioning is to use the heat of compression and condensation of the refrigeration system to heat the indoor air. The low-pressure, low-temperature refrigerant liquid evaporates and absorbs heat in the evaporator, and the high-temperature and high-pressure refrigerant gas releases heat and condenses in the condenser.
2. The control board of the air conditioner is also a kind of circuit board. Although its application range is not as broad as that of the circuit board, it is smarter and more automated than the ordinary circuit board. Simply put, a circuit board that can play a control role can be called a control board. The control panel is used inside the factory's automated production equipment, as small as the toy remote control car used by children. The control board generally includes a front panel, a main control board and a drive board.
3. Household control panels not only refer to household use, but also many commercial control panels. There are roughly these categories: home appliance IoT controllers, smart home control systems, RFID wireless curtain control panels, cabinet heating and cooling air conditioning control panels, electric water heater control panels, household range hood control panels, washing machine control panels, humidifier control panels, Dishwasher control panels, commercial soymilk control panels, ceramic stove control panels, automatic door control panels, etc., electric lock control panels, intelligent access control systems, etc.
Air conditioning is the main part of building energy consumption. The temperature and humidity independent control system should be an effective way to reduce energy consumption, improve the indoor environment, and match the energy structure. Use the indoor temperature and humidity transmitter TMT01 to detect the indoor temperature, and use the temperature regulator TC01 to control the cold water electric three-way regulating valve (diverting three-way) TV1 and the hot water electric diverting three-way regulating valve TV2 to meet the needs of indoor temperature regulation . When entering winter operation, set the "winter-summer" season switch on the TC01 temperature regulator to the "winter" season. If the indoor temperature is higher than the set value, the TC01 temperature regulator will control the hot water electric regulating valve to change The diversion ratio reduces the amount of hot water entering the air heater and reduces the indoor temperature; on the contrary, it increases the amount of hot water in the direct-flow path of the diversion three-way regulating valve to increase the indoor temperature. When running in summer, you must switch the winter-summer switch on the TC01 temperature regulator to the "summer" position. At this time, if the indoor temperature is higher than the set value, the signal is selected by the TC01 temperature regulator and SS01 signal After the device, control the cold water valve TV1 to open the DC path of the large shunt three-way; otherwise, close the DC path of TV1.

Finally, the editor recommends a temperature and humidity sensor that can be used in air conditioners. The high-precision humidity measurement sensor module-HTW-211 introduced by Gongcai.com from abroad. HTW-211 is an accurate and reliable humidity measurement sensor based on HumiChip®. The humidity output of the sensor has been temperature compensated and is a linear voltage, which can be directly connected to a microcomputer with ADC input. Specially designed molding encapsulation and coating materials can ensure durability and reliability even in harsh environments. It can be widely used in many fields such as smart home, HCPV control, industrial process control, medical treatment, automobile, environmental monitoring and so on.
