This project presents the design and implementation of a smart automation system using an Arduino microcontroller integrated with a Passive Infrared (PIR) sensor, a Light Dependent Resistor (LDR), and a temperature sensor (such as the TMP36). The primary objective of this system is to enhance energy efficiency and environmental monitoring in smart homes or rooms. The PIR sensor detects human motion to automatically control appliances like lights or alarms, while the LDR measures ambient light levels to manage lighting systems based on day or night conditions. Additionally, the temperature sensor monitors room temperature to activate cooling devices such as fans when a certain threshold is reached. The integration of these sensors allows for intelligent decision-making and real-time automation, thereby reducing manual intervention, conserving energy, and increasing comfort and security. This system is low-cost, scalable, and can serve as a prototype for broader smart home applications.
