Inside the 3D printed top enclosure is a WEMOS D1 Mini board, sitting on our custom prototype PCB. This board gives you some easy expandability to add your own sensors and hardware.
The Dust Box is using the SDS011 laser particle sensor to determine what’s in the air and the BME680 or BME280 sensor for general environmental monitoring (and VOC monitoring in case of BME680).
Just snap together the two half and plug it into a convenient USB power source, and it will be does its job… 🙂
