Communication interface is customized 485, standard MODBUS, TTL, customized 10.
Power supply 12V11, host power consumption 10W12, operating environment -12°C~60°C; <90%RH (no condensation); 86~106kPa13, storage environment temperature: -20~80°C, humidity: 0~90%RH 2.
Temperature and humidity monitoring unit The temperature and humidity monitoring unit is composed of a closed loop of two different material conductors.
When there is a temperature gradient at both ends, a current will flow through the loop, and there will be an electromotive force between the two ends—— Thermal EMF
.
Homogeneous conductors with two different compositions are hot electrodes, the end with higher temperature is the working end, and the end with lower temperature is the free end
.
When the temperature of the measured medium at the working end changes, the thermoelectric potential changes accordingly, and the thermoelectric potential is sent to the computer for processing, and the temperature value can be obtained
.
The humidity monitoring unit is generally made of polymer film capacitors
.
When the ambient humidity changes, the dielectric constant of the humidity sensitive capacitor changes, and its capacitance also changes, thus obtaining the humidity.
