Circuit Documentation

Summary

This circuit integrates various sensors, displays, and actuators with multiple Arduino UNO microcontrollers serving as the central processing units. The circuit is designed to monitor environmental parameters such as rain detection, turbidity, and soil moisture, and display information on an OLED and an LCD display. It also includes a DHT11 sensor for temperature and humidity readings, a turbidity sensor, a rain sensor, and a soil moisture sensor. Actuation is handled by hobby motors and a servomotor, and the system is powered by a combination of a solar panel and a 12V battery. The circuit's functionality is extended with an ultrasonic sensor for distance measurement and a toggle switch for manual control.
