current development status: Proof of Concept.
IoT system monitoring outdoor air quality with multiple stations, remote data collection and analytics. It can work both as a stationary or a roving unit, logging datetime, position and sensor data.
| sensor | description | physical dimensions | max connected sensors |
|---|---|---|---|
| pms5003 | PM Sensor PMS5003 | pm1.0 pm2.5 | 2 |
| pms5003T | PM Sensor PMS5003T | pm1.0 pm2.5 humidity temperature | 2 |
| sngcja5 | PM Sensor SN-GCJA5 | pm1.0 pm2.5 | 1 |
| sps30 | PM Sensor SPS30 | pm1.0 pm2.5 | 1 |
| bmp280 | Pressure sensor BMP280 | barometric pressure | 1 |
| aht20 | Humidity and Temperature Sensor AHT20 | humidity temperature | 1 |
- there is an overall max number of 2 connected PM sensors at the same time, regardless of the model. The limit is software, therefore it can be overcome.
