Intro: Arduino - LCD 1602A Automatic Plant Watering System With Soil Moisture Sensor
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. Go to the next step to find the schematic code & Parts list.

Step 1: Schematic Code & Parts List
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 +.
- 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)
