I needed simple air quality monitoring for my home, so I made this one.
Electronics:
ESP32H2 (https://www.aliexpress.com/item/1005007145799866.html?spm=a2g0o.order_list.order_list_main.5.5aa71802SahqoF)
ENS160+AHT21 (https://www.aliexpress.com/item/1005004761725413.html)
Limit switch: (https://www.aliexpress.com/item/1005006954670799.html) - connected between LEDs and ground.
LED (3x 3mm) + resistors
One extra resistror between CS and 3V3
Features:
Temperature, Humidity, CO2, TOC
Home Assistant over Zigbee connection
If anyone is interested in code I used, it's here. Schematics not needed, all connected via wires based on README in that Github PR (very simple connection)
Turning off led indicators with twisting (that is reason for limit switch, by twist you can engage limit switch).
