AutoWatering
Arduino automatic plant watering.
Further documentation will be provided in the future, once I have tested it in my own greenhouse and I'm happy with the firmware.
Although this initially started as a Mega2650 project, it has been through a few iterations, and now it's setup for the Raspberry Pi Pico W.
Features summary (some still in early stages):
- Rich touchscreen UI to control sensor intervals, how long motors turn on for, etc.
- Can control a flexible number of sensor/motor pairs. Personally I have it setup for 12 pairs.
- Temperature & Humidity readings
- Wifi enabled This is work in progresss.
- Only Adafruit IO integration is planned
- Power down to save battery
- This is a work in progress, and at the moment using a TPL5110 IC, for true power down.
I intend to organize the code and configuration so that certain features can easily be disabled. E.g:
- Remove Wifi use
- Useful if you intend to control the system through the UI only
- Remove the touchscreen and UI
- Useful if you intend to control the system through Wifi only
- Remove the temperature/humidity readings
- You don't really need it, or maybe you already have that info coming from Wifi because you already have another system publishing that info.
- Remove the need for the TPL5510 IC.
- If you plan to have the system always plugged in
