Modbus humidity sensors

Our humidity sensors with Modbus RTU reliably measure the relative humidity in indoor and outdoor areas and are ideal for use in building automation and industry. The digital Modbus interface enables fast integration, reduced cabling and parallel access to multiple measured values. Depending on the model, additional functions such as temperature measurement, CO₂ and VOC detection or switching outputs are integrated - ideal for demanding HVAC applications with central control.
