From the project

Sensor board for the AQEYE-D1 Air Quality Monitor.

AQEYE-SB-D1 is a PCB designed to hold the sensors for the AQEYE-D1 Air Quality Monitor project by CIRCUITSTATE Electronics. The board is designed to be connected to either the ESP32-S3-Touch-LCD-2.8 from Waveshare or the AQEYE-MB-D1 main board. A separate sensor board was designed to keep the sensitive components away from external interferences such as noise, heat and other effects. This also makes it easier to replace the sensors or to add new sensors in the future without having to redesign the main board. AQEYE-SB-D1 is a completely open-source hardware (OSHW) project designed in the…
