The work on “Development of automatic person detection system to control electrical fan and lights” using Microcontroller is a reliable circuit that takes over the task of controlling the room lights in museums very accurately. When somebody enters into the Museum then the light in the museum will be switched ON and count also incremented by one when any one leaves the room then count will be decremented by one. If the total count will be zero, the light will be automatically switched OFF. The microcontroller does the above job. It receives the signals from the sensors, and this signal is operated under the control of software which is stored in ROM. Pic Microcontroller 16F887A continuously monitor the sensors, A IR Sensor is which controls the switching on/off of the light when it detects the any person entered into the museum. The implementation is made simpler by using sensor to detect person. The system includes IR sensor, microcontroller, LCD display and a 5v power is supplied to run the system. The system uses a compact circuitry built around pic microcontroller programs are developed in Embedded C. Flash magic is used for loading programs into Microcontroller.
