DF Robot RS485 Infrared CO2 Sensor
The DF Robot RS485 Infrared CO2 Sensor uses advanced NDIR (non-dispersive infrared) technology to provide accurate and stable CO2 detection across a 400–5000 ppm range. With a fast 5-second response time and a status indicator LED, it ensures real-time monitoring while remaining easy to interpret. The sensor supports manual calibration, guaranteeing precision in varying environments.
Designed with an RS485 interface and Modbus-RTU protocol, this sensor integrates seamlessly with controllers such as Arduino (using the Gravity RS485 to UART module). Its IP65-rated housing, complete with a waterproof and breathable membrane, protects against dust and moisture while maintaining reliable air permeability. Compact, durable, and versatile, it is ideal for indoor monitoring, greenhouse management, pipeline detection, and fresh air systems.
