SCD41 Sensor - CO2, temperature & humidity sensor

This CO2 sensor has an integrated temperature and humidity sensor for more accurate measurements.

It is operated with 2.4 to 5.5 V and also provides a high accuracy for measuring the CO2 content (± (40 ppm + 5 %). It communicates via a digital I2C interface. The low power consumption is on average only <0.4 mA at 5 V for a measurement every 5 minutes. Thanks to its compact size (22 x 14 x 8 mm) and standard I2C interface, the gas sensor module can be easily integrated into controllers or microprocessors.

Ideal for a wide range of air quality monitoring applications!
