The following problems shall be solved with this project:
- Solar Powered
- Low Powered
- Plant monitoring
- Plant watering
- IoT
Open hardware design (powered by KiCAD). The complete PCB is stored in the board sub directory.
There the following components are connected:
- ESP32 16MB flash required
- Lipo monitoring (DS2438)
- 7 moist sensors
- 7 pump
- DC-DC convert (generating voltage from Lipo for pumps)
- DS18B20 temperature sensors
- water level via laser distance sensor (VL53L0X)
- DS2438 battery monitor
- general purpose expansion pins
The firmware for the controller is stored in esp32 sub directory.
