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.\n\nThe 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.\n\nKey Features\n\n\nDetection – Carbon dioxide (CO2) via NDIR technology\n\nMeasuring Range – 0 to 50,000 ppm\n\nAccuracy – ±(50 ppm + 5% of reading)\n\nResponse Time – T90 < 30 seconds\n\nPreheating Time – 3 minutes\n\nInterface – UART (Gravity connector)\n\nOperating Voltage – 4.5V to 5.5V DC (5V required, even with 3.3V microcontrollers)\n\nAverage Current – <85 mA\n\nOperating Temperature – 0°C to 50°C\n\nOperating Humidity – 0–95% RH (no condensation)\n\nTemperature Compensation – Built-in\n\nService Life – >5 years\n\nBoard Dimensions – 21 × 27.11mm\n\nWeight – 42g\n\n\nIdeal For\n\nIndoor air quality monitoring\nHVAC and refrigeration systems\nIndustrial process and safety monitoring\nAgricultural and animal husbandry environments\n\n\nPackage Contents\n\n1× UART infrared CO2 sensor probe (0–50,000 ppm)\n1× Sensor converter board\n1× 6-pin sensor cable\n1× PH2.0 Gravity UART cable\n1× XH2.54 4-pin header\n\n\nResources\n\nProduct wiki (DFRobot)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13985,"title":"Default Title","sku":"DF-SEN0220","price":152.43,"on_sale":false,"in_stock":true,"available_quantity":25,"option1":"Default Title"}]}
