Abstract

This paper describes the process of designing a system that controls the speed of a fan in a room with two exits based on its occupancy and the room temperature. Four pairs of infrared sensors and the LM35DZ temperature sensor detect the number of people and the temperature respectively, and the PIC16F84A microcontroller is used to control the speed of the fan based on those two inputs. The program was written using MPLAB software and the hardware was designed using Circuit Maker 2000 and Protel DXP. Rising temperatures will cause the microcontroller to increase fan speed to provide greater comfort for the room occupants. The fan will shut down when no persons are detected in the room.
