Automated heating system

The automated heating system model is controlled by the Arduino UNO platform, and consists of a temperature and humidity sensor, two LEDs (red and green), a 20×4 display (LCD) and a piezo speaker. The sensor measures the temperature and humidity and displays it in the first line of the display. If the temperature drops below 22°C, the gas pump (or electric boiler) is turned on via a relay, and the piezo speaker gives an audible signal for 1s. The ambient temperature is heated to 24°C, after which the relay turns off the gas pump or electric boiler. While the temperature is above 22°C, the green LED lights up, otherwise it is red. The model is also applicable to an air conditioner, where it is necessary to apply temperatures programmatically. The possibility of progress lies in connecting the microcontroller to a smartphone so that the user, absent from his own home, can control the temperature of his home at certain times.
