Using Energy Efficient Temperature Sensor for Automatic Control of the Heating and Cooling System in the Home
Abstract
With the development of modern technology, Smart Living is gradually changing people’s life and thus providing a necessary technology to create convenience, intelligence and controllability. In this paper, a new Smart Living system is introduced for the Automatic Control of Heating and Cooling System in the Home. The system is designed to assist and provide support in order to fulfill some of the needs of elderly and disabled in the home as the elderly and the disabled are often in dire need of controlling their home environment. The main control system employed is a temperature sensor LM35 which serves as input signal to the central processing unit, which is the microcontroller whose function is for the overall control of the system. The output unit which consists of the relays which power on and off the 60 Watts bulbs (Heating system) and the fan (Cooling system) , and an LCD (Liquid Crystal Display) which help to make the results of the test visible. The results of the test showed that the system automatically switched on and off two 60watt light bulbs and a 0.14 Amps fan at the preset temperature value (below 25oC and above 30oC) through the LM35 temperature sensor.
