AUTOMATIC SPEED CONTROLLER FOR FANS AND COOLERS



INTRODUCTION

This is a device to control the speed of fan and coolers automatically. The
device presented here makes the fan run at a full speed for pre determined time. This
speed is decreased to medium after some time and to slow then onwards after a period

of 8 hours, the fan or cooler is switched off.

The circuit consist of IC1 (555 Timer IC) which is used as an astable multi

vibrator use ....etc

During summer nights, the temperature is initially quite high. As time passes, the temperature starts dropping. Also, after a person falls asleep, the metabolic rate of one s body decreases. Thus, initially the fan/cooler needs to be run at full speed. As time passes, one has to get up again and again to adjust the speed of the fan or the cooler.The device presented here makes the fan run at full speed for a predetermined time. The speed is decreased to medium after some time, and to slow later on. After a period of about eight hours, the fan/ ....etc
