About this item

The Gravity I²C SCD41 Infrared CO₂ Sensor (400–5000 ppm) is a compact air-quality sensor built around Sensirion’s mini photoacoustic NDIR SCD41 module. Powered by 3.3–5 V and consuming under 4 mA, it outputs accurate CO₂ readings (±40 ppm + 5% of measured value) alongside temperature and humidity data, thanks to an integrated compensation sensor. The 32 × 27 × 8 mm board communicates via I²C (address 0x62) with a response time of about 60 s for CO₂ and 120 s for temperature and humidity. Its low power and compact size make it ideal for indoor air monitoring, smart ventilation, and greenhouse environments.
