Circuit Generates Analog Fan-Speed Control


Abstract:
A linear circuit measures temperature and controls the speed of a cooling fan by generating a variable supply voltage for the fan. Fan noise is becoming a larger issue as more electronic equipment enters the office and the home. A variable speed fan permits slower, and quieter, fan speed when temperature conditions allow. Fan-control circuits range from simple switches that boost the fan speed at a certain temperature, to digitally controlled fans with ....etc

fan speed control system
INTRODUCTION
Fan Tachometer
The embedded controller registers 0x84 (LSB), 0x85 (MSB) are the main fan tachometer, and report fan speed in RPM in everything since the A31 and maybe a little earlier. Not much is know about the tachometer in earlier models, or even whether they had one or not.
On the X61/X61s, one must select through EC register 0x31 bit 0 which fa ....etc

TAMPERATURE BASED FAN SPEED CONTROLLER

INTRODUCTION

Embedded systems are finding increasing application not only in domestic applications but also in areas of industrial automation, automobiles, power electronics, defence and space equipments. Micro controllers are the basic building blocks for many embedded systems. In spite of revolutionary advances in the field of electronics, micro controllers play a major role in the design of embedded control systems during the past two decades. They are available in 8- ....etc

PLEASE SEND FURTHER MORE INFORMATION ABOUT PROJECT NAMED SPEED CONTROL OF RADIATOR FAN USING DIFFERENTIAL GEAR ARRANGEMENT ....etc

[:=Read Full Message Here=:]

The features of this device are:
5 speed fan regulator, Digital display, Timer, Low temperature shutdown switch and also a Buzzer
This circ uses PIC 12F675 from Microcchip and CD D4026 (De cade Counters/Dividers +
Decoded 7 Segment Display Outtputs).


How to Operate
As IR pulses are received, circuit will count up an the increase of fan speed. speed can be controlled from 0-5.current. The seleection of the user is displayed on seven segment display also for convenience.

Timer mode:
To enter timer mode go to 6 ....etc
