HVAC Room RS485 Temperature And Humidity Air Pressure Transducer Sensor
Description of HVAC Room RS485 Temperature And Humidity Air Pressure Transducer Sensor
The HVAC Room RS485 Temperature And Humidity Air Pressure Transducer Sensor adopts high precision temperature humidity integrated chip. The HVAC Room RS485 Temperature And Humidity Air Pressure Transducer Sensor is measured by using diode temperature sensing p-n junction, and the forward step-down changes with temperature under constant current. HVAC Room RS485 Temperature And Humidity Air Pressure Transducer Sensor is measured by humidity sensitive capacitance, which changes with the change of humidity. The HVAC Room RS485 Temperature And Humidity Air Pressure Transducer Sensor are compensated for each other, and then amplified into standard digital or analog signals of relative humidity and temperature through amplification circuit.
