Joker Remote Hazardous Gas Station and Monitor

Using an IR remote control, display the presence of hazardous gases w/ MQ series sensors and get notified when they reach dangerous levels.

For a long time, I wanted to create a unique device to observe the presence of varying hazardous gases for a breadth of applications such as air quality monitoring and gas leak detection. Thus, I decided to develop this project.

First of all, to elicit assiduous gas measuring results, I chose to utilize these MQ series gas sensors by connecting them to the Arduino Nano:

- MQ-2
- MQ-3
- MQ-4
- MQ-6
- MQ-9

After choosing gas sensors for my device, I decided to control its settings and features with an IR remote control. Hence, I connected an IR remote receiver module to the Arduino Nano. Then, to display generated gas measurements, I used an ST7789 IPS screen.

Finally, I added a buzzer and a 5mm common anode RGB LED to get notified when gases reach dangerous levels.

As you may have known, the toxic gas compound manufactured by Joker (Joker Venom or Laughing Gas) is considered remarkably dangerous in DC Universe. Hence, I shaped my device inspired by Joker’s appearance in comics as a reminder of the detrimental effects of gases.

After completing wiring on a breadboard and testing the code, I designed my Joker-inspired PCB to complete my project. It became a stylish and intriguing addition to my workplace as an effective apparatus to monitor the presence of hazardous gases :)”
