Soil moisture sensor Automatic Plant Watering System

Hello world! Today i got a new Gold coated soil moisture sensor for my website and i wanted to test it of course, this sensor is a bit better then the regular on the market and the previous ones i used, the sensor is coated with gold which make them last way longer. You can add something that opens and closes with the servo to deliver a stream of water automatic, when the soil is moist enough again the device will close again.

Just wire it up like the schematic upload the code and it should work, if your servo is acting weird try to put a 450 uF capacitor between VCC and GND of the servo, like the schematic. Make sure you connect the white side which has a – on it to GND. The long leg is +.

Parts list:
Arduino uno, I always use the RobotDyn Uno.
Soil moisture sensor Gold Coated.
Servo motor
LCD 1602 With I2C
Jumper wire set MM/FF/MF
Small breadboard or proto board to add a Capacitor between VCC and GND of the Servo. (optional)
Capacitor 450 uF (Optional)
