Now here is a project I could really use here in my own greenhouse. It’s basic setup is great, but it also allows a lot of room for expansion and improvement, so it is a great learning project, too. I think it is always important to start with a simple project and experience some success so you are more inclined to fiddle with it and improve it in the future.
For me, I could see adding additional sensors for multiple pots, a solenoid value for controlling water from a hosepipe, alerts, alarms and more. What could you do with this project? Let me know in the comments!
I love this simple and clever design. It basically uses a microcontroller-powered servo motor to pinch a watering hose on/off on a gravity-fed plant watering system. No pump required. To control the system, the Norwegian maker, Eirik, used a SparkFun Arduino-compatible RedBoard. To tell when the plants are thirsty, he uses a $5 SparkFun Moisture Sensor.
Build your own projects with these Arduino parts and more!
