Smart Room Temperature Controller Atmega
As the outside temperature varies, it may affect our room temperature. So there is a need for technique to control the temperature of the room even if the outside temperature varies. Our project Smart Room Temperature Controller Using Atmega Microcontroller overcomes this problem. This project makes use 2 loads. It uses bulb to detect heater and fan to detect cooler. The system allows to maintain a specific temperature limit by continuously switching between heater and cooler i.e by alternatively turning ON/OFF the bulb and the fan. Once the system is turned ON, it displays the set temperature limit on the LCD screen. The system also includes two push buttons for increasing or decreasing the temperature. If the room temperature goes below the set limit, the system turns ON the bulb. Same way if the room temperature goes above the set temperature limit, the system turns ON the cooler. Thus by switching between the fan and the bulb, the system tries to maintain the set temperature limit that is being set by the user.
