Eltronicschool. - This is one application of PIR motion detector for mirror lights in elegant bathroom. With PIR we can design circuit schematic of Elegant Bathroom Mirror Lights with Motion Detector PIR easily.
In this time, based on PIR as audio amplifier IC, we will give you one of electronic circuit schematic of Elegant Bathroom Mirror Lights with Motion Detector PIR like in Figure 1. below.
Circuit Schematic
Component Part
Circuit schematic like in Figure 1 above is Elegant Bathroom Mirror Lights with Motion Detector PIR. the PIR motion detector might be tricky to implement. The light coming from the LED lightbulbs may mess with the ambient light sensor inside the motion detector module, and this may cause erroneous operation when the mirror is alive.
How it works
According Electroschematics site describe that the inspiration for this project came from the artwork shown here, prepared by my neighbor who is a carpenter. The project was nothing more than a bathroom washbasin mirror with a bunch of lamps around it. After some experiments with lightbulbs and rocker switches, I decided that it was a dangerous idea to have a rocker switch (made of obscure materials) connected to a fatal AC mains supply very close to my wife when her hands are soaked with water. However, I still cherished it, so to spice things up, I just revamped the concept and added some cool features.
The first part of the schematic is a transformer-less DC power supply for converting the 230-V AC input to about a 16-Vdc output. This DC output is used to power the rest of the electronics, excluding the motion sensor. The very popular, yet cheap, DYP-ME003 PIR sensor module is used here for the detection of human motion. Refer to its datasheet for technical specification, calibration information, etc. Because the module has a provision to attach one light-sensitive resistor (LDR/photoresistor/CdS cell), a 5-mm standard LDR is attached to the module after a minor mod. This drives the switch to be operational only when the detection area is sufficiently dark (the mirror lights up when one enters the darkened bathroom).
