The air conditioning controller is mainly used for air conditioning automatic on and off function, in addition, it generally also has a power failure memory function, so as we all in the daily life of the indispensable gadgets and play an important role. The number of air conditioning controllers on the market a wide variety of different manufacturers and applicable scenarios in the offer as well as the actual performance will have a slight difference, so in the purchase of the choice before the need to combine their own actual situation to filter out the most appropriate one.
AIRC485

Three, air conditioning controller circuit composition
1.Temperature Detection
Mainly room temperature (room temperature), inner coil temperature (room temperature) and temperature of the coil. ), internal coil temperature (tube temperature), external coil temperature
Temperature measurement is through the thermistor sensing temperature change after the change in resistance, the use of it and the fixed reference resistor voltage division ratio will be converted into a change in temperature to voltage changes, and then converted into a digital signal through the A/D.
The temperature measurement range of air-conditioning controller is small, generally from zero on sixty, seventy degrees to minus ten degrees, so the use of thermistor is mostly 5K3470, 10K3950 and other small resistance type.
2, humidity detection
Humidity through the humidity sensor to detect.
3, infrared remote control reception
Through the infrared receiver head to receive the infrared remote control control signals emitted by the remote control.
4?Three-minute delay protection circuit
The compressor can not be started immediately after the shutdown, the need for three-minute intervals, otherwise the compressor will produce a liquid shock phenomenon and cause damage to parts, affecting the life of the compressor. But the precision requirements of the delay is not high, can be detected through the capacitive timing to detect power outage time there is no more than 3 minutes.
5?Display output, key input circuit and other auxiliary circuits
Four, how much is the air conditioning controller
1, China's Anying Technology air conditioning controller factory direct WIFI intelligent air conditioning controller
Currently quoted at 900 yuan/unit
2, SYSGREEN network Energy-saving air conditioning temperature control system central air conditioning intelligent temperature control system central air conditioning energy-saving air conditioning controller

Air conditioning controller is compact, easy to carry, take infrared technology and the relevant intelligent setup mode, with a memory of the power outage and automatically open or close the function. Function, so as we often use in daily life and play an important role in the work, in addition, we also learned that it is on the market pricing disparity, which is mainly related to the product brand differences and models, applicable scene and so on several boards of the information difference, so you need to combine their actual needs of the budget to filter out the most suitable one.
