SM400-4-CPTH is a multi-sensor that supports MODBUS RTU protocol over the RS-485 interface. The sensor measures CO2 concentration, humidity, temperature and barometric pressure. Suitable for environmental quality monitoring, indoor air, smart ventilation systems, restaurants and breweries CO2 level and CO2 leakage control.
