Ultrasonic Hand Washing With Pir Motion Sensor

This ultrasonic led is automatic turn on and off by the help of pir motion sensor which by the help of sensing motion relay the led to open,it is desinged for multiple uses such as uv hand washing , currency checking, tool disinfection and etc.

there are two mdf 12x6 inches pieces and 10x6 inches screw them together will form a rectangle shape box and covering with a plyboard to cover on the back

I connect two bulbs in parallel and connect it with the given wires diagram to relay the bulbs

Both negative wires will be connected together but 220v power wire will go to the pir motion sensor brown wire and it's red will go to the bulb positive connection

,pir motion sensor can also be adjusted to the need I set it to the lowest time and medium sensitivity

make a hole on the center top and take out the pir motion sensor base from it and screw the bulb holders on its sides and make the wiring and secure it with electrical tape , cover the edges with wood covering and place the 4'' x 11.50'' mdf piece to hide the electrical wiring , now if I place my hands under the pir motion sensor it will turn on the uv led and If I want to make it work for longer I can change the setting just by sliding down the mdf board down and set it ,it can be useful in uv hand washing ,currency checking and tool sterilization.
