Plant watering alarm with arduino

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
