Automatic LED lighting with motion sensor

I will show how to make a universal LED illumination of something, be it at least the lighting of the working area or the illumination of the niche of the bed. The LED strip will light up automatically when the object approaches and also automatically turn off after a specified period of time.

It will be needed for the manufacture of automatic lighting


LED tape, my skein. Took a warm glow.

The sensor itself. When buying, look at the supply voltage. My feeds from 12 V. You can take the 5 V most common, but then you have to make a stabilizer for it. Immediately stabilizer is right on the sensor board.

The connector for connection has three outputs: plus, minus and logical signal output. Well, here you can guess: red - plus, black - minus, and brown - signal output.

Automation scheme


The scheme of coordination and control of the glow of the LED strip using a motion sensor is presented below.

On the chip NE555 assembled a delay timer. As soon as a short signal is received from the motion sensor, the timer will start and turn on the LED strip using the key on the transistor. But how time will come out - turn it off. It's simple.
We assemble the circuit and test it on a temporary breadboard.

Next, collect already on the permanent.

From the bottom, the circuit board is simply sealed with solder tracks. I like to assemble electronic devices on such boards, it is very simple. You can buy them - HERE.

Once again, we are testing the newly assembled automatic backlight board.

Without movement the tape is turned off.

And as soon as it is necessary to move or appear - it lights up immediately.

Apply automatic backlight


Where and where to apply the whole thing is up to you. Personally, I made such a highlight in the kitchen, and now when I come to the sink to wash the dishes - the light automatically lights up.
Also made the backlight of the bed. That's how everything is fixed.
