Arduino Plant Watering

In this video I’ll be showing you how to make this automated Arduino plant watering system.

For this project you’ll be needing the following parts:

  • Peristaltic pump
  • Arduino compatible board
  • Jumper wires
  • 200 ohm resistor
  • NPN transistor
  • A prototyping breadboard
  • Arduino compatible soil moisture sensor
  • 5 volt power supply

To begin I’ll be uploading the project code to the board, then insert it into the breadboard, followed by connecting the soil moisture sensor to a digital pin and power.

I’m then going to insert the transistor and resistor into the breadboard, completing the connections as shown in this circuit diagram.

 

With all of the connections made, we can then power up the system. When the sensor doesn’t detect any moisture, the Arduino will turn the pump on, delivering water to the plant.
