Sensors
- Bosch BME280 (Temperature, Pressure, Humidity via I²C). Works like a charm with the Bosch Sensortec BME280 driver
- Maxim MAX44009 (ambient light via I²C)
- NOVA SDS011 (PM2,5 and PM10 fine dust particles via UART). Needs post-processing when used in high humidity environments, e.g. during fog or rain. I haven't implemented that yet.
- TFA Dostmann 30x3161 (tipping bucket rain gauge / Regenwippe with reed switch). One impulse per 0.45mm (i.e., one impulse per 0.45l/m²)
- WH1080 anemometer (with reed switch). Wind speed in km/h is number of impulses per second * 2.4; IIRC it's one or two impulses per revolution.
Meta
Data collection is managed by a mains-powered Raspberry Pi 4 and a battery-powered ESP8266 board (conversion to solar energy harvesting is in progress). Their current status is:
