This upgraded version of the soil water monitor includes the ability to turn on and off a small pump (larger pumps are possible, see my video "RPi 03 - Massive Power Control Experiment"). It also allows for watering at night (based on clock time. This code will shut off the water at midnight).






MATERIALS:
- Raspberry Pi microcomputer
- Sensor module

WARNING: Electricity always carries the risk of burns, fire, shock, electrocution, etc., especially in wet environments. Mis-wiring your raspberry pi will ruin it and its peripherals. If you do not know, learn first or do not do it. This information is provided "as is" and you are solely responsible for how you use it. This setup is for demonstration purposes only.
