SEM227The integrated louver can be widely used in environmental detection. It integrates noise acquisition, CO2, temperature and humidity, atmospheric pressure and light. It is installed in the louver. The equipment adopts standard MODBUS-RTU communication protocol and RS485 signal output. The maximum communication distance can reach 2000 meters (measured). The transmitter is widely used in various occasions such as measuring ambient temperature and humidity, noise, air quality, atmospheric pressure and illumination. It is safe, reliable, beautiful, easy to install and durable
