Favorite Automatic Room Temperature Control Circuit Diagram

The controller is based on atmega8535 microcontroller which makes it dynamic and faster and uses an lcd by akshay mathur.

Automatic room temperature control circuit diagram. It has voltages operating range between 1 8v to 5 5v. By varying the set temperature periodically we can avoid making the ac to work for lower temperature values for a long time and thus making it consume less power. You can set them as output and connect them to ground preferably via a pull down resistor to avoid em interference.

3 it is seen that v r m s 9 76 v. Pic 18f45k22 has 40 pins. Contents problem statement introduction methodology circuit diagram components applications conclusion references 2.

Once we tune the sensitivity temperature level this circuit becomes automatic temperature controlled switch this circuit requires few affordable components and can be prototype with the dot board. It has low power consumption. Thus there is a prevalent use of a air.

The terminals ratings of the relay should depend on the power of the. Automatic temperature control circuit diagram. Components of automatic temperature controller system.

Here is an easy to construct temperature indicator cum controller that can be interfaced with a heater coil to maintain the ambient room temperature. The base emitter voltage of t2 decrease by 2 mv per 0 c. T2 should not conduct as long as the temperature level being monitored is below the set threshold.

First stage of this circuit is rectifier and regulator unit high voltage ac 110 220v supply is reduced to 9v ac with the help of step down. It has 1536bytes ram. It is best for such projects.
