IoT based Soil Moisture Monitoring System with ESP32 and Adafruit IO
In this tutorial, we will build an IoT based soil moisture monitoring system with ESP32 and Adafruit IO. Firstly, we will show you how to interface soil moisture sensor e.g. HL-01 with ESP32. Not only that but we will build a soil moisture monitor that will indicate the percentage of moisture in soil on the … Read more
