Air quality sensor integration board that couples together the following modules:

- ESP32 TTGO T-Display module

- PMSA003 module

- BME680 CJMCU module

I use this to track the AQI in my home.  This sensor measures within 1% of 3x different [PurpleAir sensors

scattered around my

neighborhood](https://www.purpleair.com/map?opt=1/i/mAQI/a10/cC0#12.69/37.74937/-122.43828).  The PMSA003 particulate air sensor module in this build should be an

improved version the PMS5003 found in the [PurpleAir

sensors](https://www2.purpleair.com/collections/air-quality-sensors).

Combined with [Home Assistant](https://www.home-assistant.io/), [InfluxDB](https://www.influxdata.com/),

and [Grafana](https://grafana.com/) I can track the long term air quality inside and outside my home.

## TODO

### Hardware

- [x] Design Kicad schematic + PCB

- [x] Release Gerbers

- [x] Order PCBs from [PCBWay (use my referral code "3549" to save $5)](https://www.pcbway.com/setinvite.aspx?inviteid=3549)

- [x] Photograph real PCB + PCBA

- [ ] Add pin labels to silk screen

- [ ] Route out hole for TTGO T-Display battery connector so it fits flatter

- [ ] Find someone to make a 3D printable enclosure

### Software

- [x] Upload ESPHome YAML file
