## Description

The Gravity UART Infrared CO2 Sensor uses non-dispersive infrared (NDIR) technology to measure carbon dioxide concentrations from 0 to 50,000 ppm. It offers excellent selectivity with no oxygen dependency, built-in temperature compensation, and a service life of over 5 years. The UART interface makes it compatible with Arduino, Raspberry Pi, and other microcontrollers. The sensor features high sensitivity, fast response, and resistance to water vapour interference — making it suitable for HVAC monitoring, indoor air quality, industrial safety, and agricultural process control. Key Features Detection – Carbon dioxide (CO2) via NDIR technology Measuring Range – 0 to 50,000 ppm Accuracy – ±(50 ppm + 5% of reading) Response Time – T90 < 30 seconds Preheating Time – 3 minutes Interface – UART (Gravity connector) Operating Voltage – 4.5V to 5.5V DC (5V required, even with 3.3V microcontrollers) Average Current – <85 mA Operating Temperature – 0°C to 50°C Operating Humidity – 0–95% RH (no condensation) Temperature Compensation – Built-in Service Life – >5 years Board Dimensions – 21 × 27.11mm Weight – 42g Ideal For Indoor air quality monitoring HVAC and refrigeration systems Industrial process and safety monitoring Agricultural and animal husbandry environments Package Contents 1× UART infrared CO2 sensor probe (0–50,000 ppm) 1× Sensor converter board 1× 6-pin sensor cable 1× PH2.0 Gravity UART cable 1× XH2.54 4-pin header Resources Product wiki (DFRobot)
