A reminder to ventilate regularly is useful for health, comfort and well-being. Poor indoor air quality can lead to decreased productivity and learning disabilities. Therefore, I developed an ESP32 project that uses an E-Ink display to show the indoor CO2 content. Comparable commercial meters cost significantly more and have fewer features.
With the SCD40, Sensirion offers a completely new miniaturized CO2 sensor based on the photoacoustic sensor principle. The integrated, industry-leading humidity and temperature sensor offers high accuracy with low power consumption.
1.54" in size, with 200x200 pixel resolution and low power consumption with wide viewing angle. Per partial refresh, readings are updated every five seconds.
For displaying the air quality as a traffic light (green, yellow, red, magenta). Brightness and color are adjustable via software.
size: 47 x 41 x 24 mm
By means of the ESP32-S2 processor on a self-designed PCB, a Wifi connection is available.
