In this tutorial, our projects comprehensively apply all sensors and modules in the kit, like photoresistor, soil humidity sensor, water level sensor and ESP32 wireless communication module. As a result, by learning this tutorial, you can possess the knowledge that how to ...
If the soil is dry and the soil temperature is appropriate for watering, the ESP32 opens a solenoid valve and waters the plants. The amount of time to run the drip irrigation system is determined based on the flow rate measured by the water flow sensor. The ESP32 reads the humidity ...
