SOC-H1 - Outdoor


Active humidity sensor for outdoor mounting

The SOC-H1 measures the relative humidity with a unique capacitive sensor element. The microprocessor samples the humidity once per second. It calcualtes an averaging signal over a preset number of seconds and generates the output signal.

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