Wireless Modbus humidity sensors

Our humidity sensors with W-Modbus enable wireless and precise monitoring of relative humidity in rooms, ducts or weather-protected outdoor areas. The devices can be quickly and flexibly integrated into existing building automation systems - without any cabling.

Thanks to the manufacturer-independent W-Modbus technology, you benefit from reliable, fast data transmission and noticeably lower installation and maintenance costs. Ideal for modernizations, installation locations that are difficult to access or flexible HVAC solutions with minimal effort.
