Air-quality sensor (CO2, particulate matter, ...) in a nice 3D printed package with LED bar visualization. Using ESPHome, compatible with HomeAssitant.
- Wi-Fi
- RGB LED bar for quick visual air-quality indication
- HomeAssistant compatible
- Accurate CO2 using dual NDIR sensor (SCD30)
- Particulate matter (<10µm, <2.5µm, <1µm)
- Temperature
- Humidity
- Illumination (amount of light)
- VOC (Volatile organic compound) sensor
- NOx sensor
Manufactury files available, see schematic/jlcpcb. They can assemble most of the bord, however you'll need to solder at least CO2 sensor & particulate matter sensor yourself.
