Nowadays, environment getting warmer because of human activity like illegal logging. People are not aware or alert on temperature in the house. To overcome this situation, a device that can control the temperature in house is developed. Temperature control will detect the temperature limit that have been set by owner and the other tool to cool down the temperature will active if the temperature reach higher than the temperature that have been limited. This is the summary of how our project work. The temperature limit can be set by user . The process begin when the device is tum on. The LCD display shows a current temperature which is effect temperature and reference temperature which is the temperature that has been setup . Therefore, the prototype should maintain the temperature. If the temperature sensor detects the temperature deviate from the temperature that have been setup, the controller generates an output signal to activate the temperature back to cool down the temperature. For instant, when the temperature exceeds higher limit then the system should switch ON the LED in blinking states and LCD display will show the current temperature of the device. Furthermore, the buzzer will automatically start working and fan start the rotation. That situation will inform the users should alert on current temperature. Next, if the temperature sensor detects the temperature falls below the setup temperature, then the system should switch OFF the LED and LCD display will show the current temperature of the device. Buzzer and DC fan also not active
