Modbus air quality sensors

Our air quality sensors with Modbus RTU reliably record important indoor air parameters such as CO₂, VOC, temperature and humidity. Thanks to the digital Modbus interface, the devices can be easily integrated into modern building management systems - ideal for energy-efficient ventilation strategies and compliance with legal indoor air requirements. Depending on the model, the sensors offer additional outputs, switching functions or an integrated display for direct on-site indication of the air quality.
