Abstract

Conventional cooling, also known as a fan, is a common solution for maintaining a comfortable room temperature. This cooling system is used by many companies or factories for the comfort of workers. Manual operation of these coolers is often inefficient and less accurate in temperature settings. Therefore the author created a control system to turn on the 2nd motor (fan) because the 1st motor (fan) remains on without being regulated by any sensor, when the temperature is detected as hot, namely >=30°C then the 2nd motor (fan) turns on and Turns it off again when the temperature is detected as cold, namely <=25°C by the DHT 11 sensor. It is controlled by the L298N DC module. Initially the motor (fan) was off, now it turns on and vice versa depending on the temperature sensor that detects the room. There is also an LCD to display the value results from the DHT 11 temperature sensor. This conventional cooler can be operated in any room, including cold rooms because it can automatically turn off. This conventional cooler can be operated in any room, including in a cold room because it can automatically turn off.
