The project tells you about interfacing soil moisture sensor and LCD to give display. I forget everyday to water my plant and my grandmother used to recall me to water. So now I think I should build a project to show moisture so I remember that I have built project lets check out the moisture. So I quickly opened Circuito.io and added inputs and outputs and got schematic.
Connecting Moisture Sensor
- Connect Soil Moisture 0 to GND.
- Connect Soil Moisture Sig to Arduino A3.
- Connect Soil Moisture Vin to Arduino 5v.
- Connect LCD SCL to Arduino A5.
- Connect LCD SDA to Arduino A4.
