Arduino project for plant watering by humidity levels, that includes a phone app that connects the Arduino board by bluetooth
1X Arduino UNO
2X Ground humidity sensor
1X Air humidity and temperature sensor
1X Solenoid valve
1X Ldr light sensor
1X Stepper motor
1X HC-05 bluetooth module
1X Relay
The app was made using MIT App Inventor blocks and design
This part was made to make sure that only the plants that need water will get it.(Let's say part of the plants need less water or less exposed to the sun.) The connection was made by a screwdriver, Coca-Cola cork and hard electricity wires.
The plant watering can be fully automatic, It works on ground humidity and light exposure. If the ground is dry and it's night time, The system will be activate. The android app is a way to pass the automatic system and water the plants when ever you like to.
