Using Arduino to read the soil humidity sensor, then send the value to the app using Serial connection over Bluetooth.
Getting started
Hardware
Components needed
- Maker UNO – also possible to use any Arduino
- Bluetooth Serial Transceiver HC-05
- Moisture Sensor Module
- Micro Submersible Water Pump DC 3V-5V
- Single Channel 5V Relay
- Breadboard/jumper wires etc.
Code
Open arduino/arduino.ino file and upload the code.
For other microcontrollers other than Arduino Uno, you may needed to change the pin etc.
Circuit
Software (App)
Kindly read the readme in soil_humidity_app folder.
