The SCD41 Gas Sensor Module Blue is a high-precision sensor module designed to measure carbon dioxide (CO₂), temperature, and humidity for indoor air quality monitoring. It features an integrated temperature and humidity sensor that provides automatic compensation, helping improve the accuracy of CO₂ measurements. With a measurement range of 400 to 5000 ppm and high accuracy of ±(40 ppm + 5%), the module is suitable for monitoring indoor environments and ventilation systems.
The module operates from a 2.4V to 5.5V DC supply and features a 2.54mm pin header for convenient integration with compatible development platforms. Its low average power consumption of 0.4mA (1 measurement every 5 minutes @5V) makes it ideal for energy-efficient air quality monitoring, smart ventilation control, HVAC systems, IoT devices, classrooms, offices, and other indoor environmental monitoring applications.
Features :
- High-precision CO₂ measurement with the SCD41 gas sensor module.
