## Description

The Gravity SCD41 Infrared CO2 Sensor provides accurate carbon dioxide, temperature, and humidity measurements in a single compact module. Based on Sensirion's SCD41 sensor, it uses photoacoustic NDIR (non-dispersive infrared) sensing with patented PASens and CMOSens technology for high accuracy in a remarkably small form factor. CO2 is a key indicator of indoor air quality — elevated levels can compromise cognitive performance and well-being. This sensor detects CO2 concentration by measuring infrared light absorption, with on-chip signal compensation from the built-in temperature and humidity sensor for reliable readings. Key Features Three-in-One Sensing – Measures CO2, temperature, and humidity from a single module Photoacoustic NDIR Technology – High accuracy with ultra-low power consumption I2C Interface – Gravity connector for easy integration with Arduino, Raspberry Pi, and other microcontrollers Low Power – Average current under 4 mA, suitable for battery-powered applications Compact Design – Just 32 × 27 × 8 mm PCB dimensions Long Lifespan – Over 10 years of reliable operation CO2 Specifications Measurement Range – 400–5000 ppm Accuracy – ±(40 ppm + 5% of measured value) Response Time – 60 s Temperature Specifications Measurement Range – −10 to 60 °C Accuracy – ±0.8 °C Response Time – 120 s Humidity Specifications Measurement Range – 0–95% RH Accuracy – ±6% RH Response Time – 120 s General Specifications Power Supply – 3.3 V to 5 V Average Current – <4 mA I2C Address – 0x62 Operating Temperature – −10 to 60 °C Operating Humidity – 0–95% RH (no condensation) PCB Dimensions – 32 × 27 × 8 mm Ideal For Indoor air quality monitoring Greenhouse environmental monitoring Smart ventilation and HVAC systems IoT environmental sensing projects Package Contents 1× Gravity SCD41 Infrared CO2 Sensor 1× Gravity 4-Pin I2C/UART Sensor Cable Resources Product Wiki Schematics (PDF) Dimensions (PDF) Design-in Guide (PDF)
