DIY IR Trip Sensor based Stairway LED Lighting

Instructables member ElJefeUno brought an awesome electronics project of building an Infra-red (IR) light trip sensor to light up your stairway. The sensor uses a directional IR LED beamed at a sensor that shoots past where you’ll walk. When you interrupt the light from the LED, the LEDs turn on for a period of time that you can adjust.

Advantages of using IR LEDs includes: safe operation, low power consumption, no harmful emission etc.

ElJefeUno in this tutorial has covered the entire process flow involved in turning his idea into reality. Check out this tutorial if you are really having the curiosity to build this project now. To gain some more curiosity watch this video where he captured his amazing concept.
