Circuit Documentation
Summary
This circuit consists of an ESP32 microcontroller and a soil moisture sensor. The soil moisture sensor is used to measure the moisture level in the soil, and the ESP32 processes this data. The sensor is powered by the 3.3V output of the ESP32 and shares a common ground. The sensor's signal output is connected to one of the analog input pins of the ESP32.
