"Smart Home" sub-modul

Smart Home sub-module This module is the first step in creating a so-called Smart Home plan. It focuses on heating the house to prevent any potentially hazardous accidents. Required equipment includes an Arduino ATmega328P, an MQ2 sensor for detecting CO, LPG, and smoke levels, a DHT22 sensor for temperature and humidity readings, an Arduino relay, a WH2004L 20x4 display, and three red LED lights. I designed a custom case to house all the components using my Anet E10 3D printer. The case was printed with PLA and PETG materials. The main unit consists of the Arduino display and three LED lights. It should be placed in a central location such as the living room, kitchen, or bedroom. The DHT22 sensor measures the boiler's temperature, which is displayed on the lower section of the display. This section is attached to the boiler's outgoing pipe with a clamp. The upper section displays the boiler room's/house's smoke, CO, and LPG levels, indicating "LOW" or "HIGH" signs. The MQ2 sensor measures these levels. If they exceed specified limits, the LED lights flash, and the display shows a warning message. In case of danger, the relay module becomes active, turning on one or more fans as part of the house's ventilation system to prevent accidents. A text appears on the display when the fans are turned on. As a mechanical engineer, this project was an exciting and challenging task for me. I enjoyed programming and working with fine electronics during this project. My goal is to complete the full Smart Home module.
