CO2 Sensor

Product serial number

Product Description

The transmitter uses a new type of infrared verification technology to measure CO2 concentration. The response is fast and sensitive, which avoids the life and long-term drift of traditional electrochemical sensors. It is widely used in agricultural greenhouses, flower cultivation, edible fungus cultivation, etc. that require CO2 and temperature and humidity. Monitoring occasions. 485 communication, standard ModBus-RTU communication protocol, communication address and baud rate can be set, the longest communication distance is 2000 meters. The equipment has 10-30V wide voltage power supply, and the enclosure has a high protection level, which can adapt to various harsh conditions on site.
