Detailed Images Products keywords co2 sensor Supply power: 10~30V DC Signal output 4~20ma/0~5V/0~10V/RS485(Modbus-RTU) Protection level IP65, can be used for snow and rain environment Working environment 0 ~ 70 â??, 0 ~ 95% RH (no condensation) Temperature effects comes with temperature compensation CO2 Measurement range 0 ~ 5000ppm (can be customized) CO2 Accuracy �± (40ppm + 3% F �· S) (25 â??) Maximum power consumption RS485 0.4W 4-20ma/0-5v/0-10v 1.2W American brand chip, warranty 2years, communication distance 2000m. RS485 or 4-20ma,0-5v,0-10v for optional The transmitter adopts the new infrared verification technology to measure the CO2 concentration, and the reaction is quick and sensitive, avoiding the life of the traditional electrochemical sensor and the long-term drift problem. It is widely used in agricultural greenhouses, flower cultivation, edible fungi planting, etc., requiring CO2, temperature and humidity. The occasion of monitoring.Having Analog or 485 communication, standard ModBus-RTU communication protocol, communication address and baud rate can be set, the farthest communication distance is 2000 meters. The equipment is 10-30V wide-voltage power supply, and the enclosure has a high degree of protection, which can adapt to various harsh conditions on site.
