AUTOMATIC WASH BASIN TAP With LED Light
Electronics For You
|July 2024
When waking up at night to use the wash basin, you may struggle to find the switchboard to turn on the light before opening the wash basin tap to wash your hands.
To help, this automatic wash basin tap with built-in LED light has been designed using an IR module and 555 timer IC. The IR module is a very simple and compact device, which has transmitting and receiving IR LEDs and a comparator.
This device opens the wash basin tap automatically and switches on the LED light fitted above the wash basin when one reaches in front of the wash basin. The wash basin tap and the LED light turn off automatically after a set time.
Circuit and working The circuit diagram of the device is shown in Fig. 2. It is built around a 230V AC primary to 12V, 500mA secondary transformer (X1), a bridge rectifier (BR1), an IR module connected across CON2, 5V voltage regulator LM7805 (IC1), timer NE555 (IC2), and a few other components.
