- A Raspberry Pi water sensor is used to check whether or not a plant has enough water1. The moisture sensor checks every half hour and communicates with the Raspberry Pi. Water flow is controlled by the solenoid valve, and if the Raspberry Pi finds the soil is too dry, it opens the valve for a set amount of time to let water out1. The water sensor has to be connected to the GPIO pins2. The setup allows reading high or low on GRIO 17 (pin 11) according to the status of the water sensor2.Learn more:✕This summary was generated using AI based on multiple online sources.

The setup from fig. 3 allows reading high or low on GRIO 17 (pin 11) according to the status of the water sensor. When water is detected, the relay closes and pulls GPIO 17 from 3.3 V (high) down to GND. Alternatively, a sensor can be connected to GPIO 18 (pin 12) accordingly.www.instructables.com/Raspberry-Pi-water-alarm-s…
