SOC-H1T1 - Outdoor


Active humidity / temperature transmitter for outdoor mounting

The SOC-H1T measures the relative humidity with a unique capacitive sensor element while temperature is measured by a band-gap sensor. The microprocessor samples the humidity once per second. It calcualtes an averaging signal over a preset number of seconds and generates the output signal based on lower and upper signal range values. 

A version with a display is possible by ordering the integrated display accessory OPC-S.
