Circuit Documentation

Summary of the Circuit

This circuit integrates various sensors with an ESP32 Devkit V1 microcontroller to monitor environmental conditions. The sensors include a PIR sensor for motion detection, a DHT11 for temperature and humidity readings, a Soil Moisture Sensor for detecting the moisture level in soil, a RAIN SENSOR for detecting rainfall, and a Water Level Sensor for measuring the level of water. The ESP32 Devkit V1 serves as the central processing unit, reading data from the sensors and potentially acting upon that data. The circuit is designed for applications such as weather stations, smart agriculture, or home automation systems.
