The 7Semi SCD41 CO₂, Temperature, and Humidity Sensor Breakout Mini utilizes Sensirion's SCD41 sensor to provide precise measurements of CO₂ levels (400–5,000 ppm), temperature, and humidity. It features a compact design, I²C interface, and low power consumption, making it ideal for applications like indoor air quality monitoring and HVAC systems.
Features:
High CO₂ Accuracy:
- Measurement range: 400-5,000 ppm
- 400-1,000 ppm: ±(50 ppm + 2.5% of reading)
- 1,001-2,000 ppm: ±(50 ppm + 3% of reading)
- 2,001-5,000 ppm: ±(40 ppm + 5% of reading)
Humidity Measurement:
- Typical relative humidity accuracy: ±6 %RH
- Operating range: 0 - 95 %RH
- Response time (τ63%): 90 seconds
Temperature Measurement:
