Automatic temperature controller / Nor Jasmi Ab. Rahman and Roszalizan Ab. Rahim

Today we actually on the go the new era of technologies. Time change and everyone try to find something different from others, especially the latest technology. Computing, communication, information technology and micro-electronic are the most interested field that scientist concentrate for.
Thus we try to familiarise ourselves with the part of this technology by construct the project which use the thermostat to detect or maintain the temperature of the load. It system have two preset level higher and lower level.
For our project, we use 18V DC supply, a few passive component such as resistor, capasitor and diode. We also use some active component such as Linear Ics and transistor. Another component we use is relay, thermostat and buzzer. These entire components are easy to get from our local electronic component supplies.
Finally we can saw the same application in the heater, iron and also at air condition.
