A device that warns us with light sound and a sign when our plant needs water. The project was made by the students of the “Little Hackers” evening club of the Experimental Elementary School of Florina. The device contains a moisture sensor, a servo motor a led light and a buzzer.
The moisture sensor is placed the plant pot and continuesly reads the moisture values. When that values fall under a certain limit the device warns us by:
- Blinking the led light
- Sending a beeping sound from the buzzer
- Turning the small sign so that the “No water” sketch is shown
