7Semi SCD41 CO2, Temperature and Humidity Sensor Breakout Mini

The 7Semi SCD41 Sensor Module is a compact and easy-to-use sensor for measuring CO₂, temperature, and humidity. It gives accurate digital output, so it is simple to use in IoT and monitoring projects. The sensor is fully calibrated, so no extra setup is needed. With low power usage and small size, it is perfect for indoor air quality monitoring, smart homes, and HVAC systems.

Accuracy -: ±(50 ppm + 2.5% of the measured value) between 400 ppm and 1,000 ppm; ±(50 ppm + 3% of the measured value) between 1,001 ppm and 2,000 ppm; and ±(40 ppm + 5% of the measured value) between 2,001 ppm and 5,000 ppm.

Features:

• CO₂ Measurement: Detects CO₂ from 400 to 5000 ppm

• Good Accuracy: Reliable readings for air quality monitoring

• Temperature & Humidity: Measures both along with CO₂

• I2C Interface: Easy communication with microcontrollers

• Fully Calibrated: Ready to use, no calibration needed

• Low Power Consumption: Suitable for battery devices

• Stable Performance: Consistent and reliable readings

• Ideal Use: Smart home, HVAC, indoor air quality, IoT projects
