Temperature Controlled Fan Using Micro controller 8051/8052 ( C Program)
I have recently made a temperature controlled DC fan whose speed increases with the rise in temperature and decrease as the temperature falls ! It has got a lot of practical usage as it does not require to manually operated and it turns off as the temperature falls below a certain threshold ! and the temperatures on which you want to change the speed or turn off the fan are completely user defined !!
The components required are:
1.AT89S51/AT89S52
2.ADC0804
3.LM35
4 ....etc

embedded temperature based fan speed controller using 89c51 microcontroller

Abstract

Temperature controller can be done by using Electronic circuit, Microprocessor or microcontroller. Now microcontroller is advanced among all above circuits therefore we are using Microcontroller for temperature controlling.In this project, microcontroller 89s51 forms the processing part, which firstly receives data from ADC. ADC receives data from temperature sensor through amplifier. Then microcontroller 89s51 performs the comparison of current temperature a ....etc

PLC BASED PROTECTION AND INTERLOCKS SYNOPSIS

A programmable logic controller (PLC) is an industrially hardened computer based
unit that performs discrete or con tenuous control function in a variety of processing
plant and factory environment. PLC consists of CPU, input device, output device and
Programming device. PLC replaces relays, timers, counters and sequencers.
Our project concerns with PLC based protection and interlocks for
1. Boiler feed pumps.
2. Mill and feeder interlocks.
3. Slag conveyor ....etc

The boiler its self is 3 - 4 years old, it lost its pressure within a week of having it installed, the fitter came out turned a couple of valves & it has worked ever since until about 4 weeks ago, now the boiler does not kick in ever without me manually turning the valves to raise the pressure. the boiler ( heating & hot water ) will remain on all day, turn off when the timer is set but then will not come back on again the next morning until I manually repeat to turn the valves. ....etc
