SN-3002-CO2-N01 Carbon Dioxide Sensor RS485 0-5000ppm (NDIR CO2 Sensor Module)

The SN-3002-CO2-N01 Carbon Dioxide Sensor is a high-precision NDIR (Non-Dispersive Infrared) CO₂ sensor designed for continuous carbon dioxide monitoring in industrial, commercial, and environmental applications. Featuring an RS485 communication interface, a standard measurement range of 0–5000ppm (expandable up to 10000ppm), and built-in temperature compensation, this sensor delivers accurate, stable, and reliable CO₂ measurements. Its rugged ABS enclosure and wide 4.5V–24V DC operating voltage make it ideal for smart agriculture, HVAC systems, indoor air quality monitoring, and IoT applications.
