Industrial Infrared CO2 Sensor, UART, 0-2000ppm to 0-100% Vol

Professional industrial CO₂ gas sensor supporting UART and 0.4–2V signal output. Features a 3.6–5VDC low-power design with response times as fast as 30 seconds. Measurement range options include 0–2000ppm to 0–100%Vol. IP54 protection rating ensures reliable operation in high-humidity and high-temperature environments, meeting long-term online monitoring requirements.

Feature

• High-precision non-dispersive infrared detection technology ensures rapid and stable CO₂ concentration monitoring across the 0-2000 ppm to 0-100% Vol range.
• The SUCH industrial CO₂ sensor features temperature compensation, maintaining precise output even in complex environments ranging from -20°C to 60°C.
• The output signal supports both UART and 0.4~2V voltage interfaces, offering strong compatibility, with an IP54 protection rating.

Dimension (unit: mm)

Analog Voltage Output

• Vout output voltage range (0.4~2V) corresponds to gas concentration (0~full scale).
• Connect the CO2 sensor's Vin terminal to 5V, GND terminal to power ground, and Vout terminal to the ADC input.
• After the preheating period, the sensor outputs a voltage value representing gas concentration from the Vout terminal.
• When a fault is detected during self-test, the CO2 sensor outputs a voltage of 0V.
