This project proposes automatic detection of human and energy saving room architecture to reduce standby power consumption and to make the temperature of the room easily controllable with an ir sensor and lm35 temperature sensor using air conditioner.
Main objective of this project is to develop a temperature control system which is provide remote system for varying temperature according to requirements.
Where the temperature is automatically adjusted as per the input settings.
Now we ll learn how to make a closed loop temperature control system.
We commonly use temperature control systems in air conditioners refrigerators geysers etc.
The idea is based on the problem occurs in human s life now a days by improving the existing technology.
