on video How To Make Motion Sensor Light Switch using CD4017 & IR sensor at Home

In this 4017 project, I have shown how to make motion sensor light switch using CD4017 & IR sensor for the washroom. I have made the complete motion sensor circuit on a homemade PCB and use this circuit as the automatic washroom light switch.  When anyone enters the washroom the IR sensor senses the motion and turns on the light and when he or she exit from the washroom the IR proximity sensor again senses the motion and accordingly turns off the light automatically.

During the tutorial video, I have shared the complete 4017 ic project circuit diagram, so after watching the video, you can easily make this simple motion sensor project using 4017 IC and use it as motion-activated light or motion-activated alarm.


Required components for the CD4017 project
1) CD4017 IC
2) LM358 IC
3) BC547 Transistor
4) 100uF 25V Capacitor
5) 1000uF 25V Capacitor
6) 220-ohm 0.25watt Resistors - 4 no
7) 10k 0.25watt Resistor
8) 10k Trimmer
9) LED 5mm - 2no
10) IR LED pair (Detector & Emitter)
11) 1N4007 Diode
12) 5V SPDT Relay
13) Connectors & IC Base
14) Acrylic sheet

I have used the 5V mobile charger to supply the circuit. Please take proper safety precautions while working on 110V or 230V AC.

You can also adjust the sensitivity of the motion sensor using the 10k trimmer.
