Designing and building a Smart Garden seems to be an easy thing to do but, as usual there are some pitfalls.

Plan ahead and save time, money and grow more in your garden.

This is a list of parts used in our garden and by no means we think it's the best or proven to be best choice of parts:
- Raspberry Pi (any model)
- NodeMcu Lua WIFI ESP8266 CP2102 (or any other flavor of ESP8266) for Soil Moisture Sensor

- Capacitive Soil Moisture Sensor


- Ultrasonic Module HC-SR04 for water level measurement



- JBtek 8 Channel DC 5V Relay Module



- AC-DC 12V Power Supply


- 1/2" 12V DC Electric Solenoid Valve, Normally Closed


- Micro Water Pump Submersible Motor 12V 1.2A DC 5M 14L/Min 600L/H 6-15V (optional)



- APC Back-UPS 125 VA 75 Watts (optional)
- 1/2" PVC pipes
