Measures temperature and humidity / output as standard signal / compact

Modbus RTU interface / wall mounting

The humidity sensor PCE-P18 is used in HVAC technology to monitor humidity and temperature. The measured values ​​are output by the humidity sensor PCE-P18 via the RS485 interface. In this compact humidity sensor, air humidity and temperature are precisely determined using a semiconductor component. For commissioning, the humidity sensor PCE-P18 is supplied via a DC voltage. The measured variables are output via a two-wire line. All connections are made via screw contacts in the waterproof IP 65 housing. This function is particularly useful if several measuring points are to be linked to one another during your home surveillance.
