“Now I’ll quickly demonstrate how our system works in real time.

Here we have our setup: This is the motion sensor, which detects human presence. This is the ESP32 microcontroller, which acts as the brain of our system. And these are the relay modules, which control the electrical appliances like lights and fans.

Step 1 – Normal Operation: Right now, as you can see, I’m standing in front of the sensor. The system detects my presence, and the light remains ON.

Step 2 – No Presence Detection: Now, when I move away from the sensor… (after a few seconds delay) the system automatically turns OFF the light.

This shows how energy is saved when a room is unoccupied.

Step 3 – Smart Monitoring (if you have dashboard): At the same time, our system is tracking energy usage. Here on the screen, you can see the real-time data of power consumption.

Step 4 – Manual Control (optional): We can also control appliances manually using a mobile interface, which adds flexibility along with automation.

Key Highlight: This entire process happens automatically without human effort, reducing unnecessary power usage efficiently.

So in real-world conditions, this can significantly reduce electricity wastage in places like hostels, classrooms, and offices.
