Once the required moisture level is reached, the system automatically turns off the pump.
This intelligent approach helps prevent both overwatering and underwatering, which are common issues in traditional irrigation methods. The project can also be enhanced with IoT capabilities, allowing users to monitor soil conditions remotely and control irrigation through a mobile interface. It is especially useful in agriculture and smart farming, where efficient water management is critical. Students working on this project gain knowledge in sensor interfacing, automation logic, and sustainable engineering practices.

Overview
The Automatic Street Light Control System is a simple yet highly effective project focused on energy efficiency. It uses an LDR (Light Dependent Resistor) to detect ambient light levels and automatically control street lights. During the daytime, when sunlight is sufficient, the system keeps the lights off. As the light intensity decreases in the evening, the system automatically switches the lights on.
This eliminates the need for manual operation and ensures that energy is used only when necessary. The system can be further enhanced by adding motion sensors to activate lights only when movement is detected, making it even more efficient. This project is widely used in smart city applications and helps students understand sensor-based automation and energy-saving techniques.
