Description 4-20mA Wall mounted temperature humidity transmitter sensor with RS485
The temperature and humidity transmitter is suitable for indoor environmental temperature measurement. Operators are responsible for checking whether the equipment is suitable for operating conditions.The sensor adopts high precision temperature humidity integrated chip. The temperature is measured by using diode temperature sensing p-n junction, and the forward step-down changes with temperature under constant current. Humidity is measured by humidity sensitive capacitance, which changes with the change of humidity. The temperature and humidity are compensated for each other, and then amplified into standard digital or analog signals of relative humidity and temperature through amplification circuit.
