Controlling Relay with IR Sensor using Raspberry Pi | Home Automation Project
In this video, we demonstrate how to control a relay state using an IR sensor with Raspberry Pi. This project is a simple yet powerful example of home automation and IoT applications.
We’ll cover:
🔹 Interfacing an IR sensor with Raspberry Pi
🔹 Controlling a relay module for switching devices (Like: a Bulb or Fan)
🔹 Step-by-step coding and circuit explanation
This experiment is part of the IoT Laboratory experiments (JNTUA) and is ideal for beginners in Raspberry Pi, IoT, and home automation projects.
