DESIGN AND CONSTRUCTION OF AN AUTOMATIC BATHROOM LIGHT
ABSTRACT
This project is on design and construction of an automatic bathroom light. The system automatically turns ON bathroom light when the bathroom door is opened, and remains lit in the occupied state. When the door is opened again the lamp turns off after a very short delay. This automatic circuit saves energy and greatly assists your visitors, especially at night. The “single-chip” circuit, built around the popular decade counter CD4017 (IC1), is very compact, and can be powered from any 5VDC/500mA mobile phone travel charger/similar smps adaptor. After construction, try to enclose the whole circuit in a suitable plastic case for total convenience. Next, arrange the door switch (S1) such that when the door is closed it should be in closed state.
