Demonstration of Motion Sensor Circuit. By following the 555 timer motion detector circuit diagram given above, I created the circuit on perf-board, the video of which is available at the end of the ...

IoT-based Smart Home Automation using the new Blynk 2.0 ESP32 LDR & temperature sensor to control an 8-channel relay module from the manual switch, IR remote & smartphone using the Blynk IoT App.

The circuit involves a PIR sensor as the motion detector, a relay to control the power to the bulb, and a transistor to drive the relay. The PIR motion sensor light wiring diagram is shown below. The ...

In this IoT project, I have shown how to make IoT-based Smart Home Automation using ESP32 Google Assistant Blynk with the timer, sensor, and IR remote control relay with real-time feedback. So, you ...
