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.
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
Important power note: When powering the board through VCC, the 3V3 pin acts as the regulated 3.3V output. Alternatively, the board can be powered directly through the 3V3 pin. Do not apply power to both VCC and 3V3 at the same time.
