The inspiration for our flammable gas detector project came from the need for a reliable and efficient solution to detect and prevent potential fire hazards caused by flammable gases in various environments, such as homes, laboratories, and industrial settings. We recognized the importance of early detection and timely alerts to mitigate the risks associated with flammable gases and ensure the safety of people and property.

What it does:

Our flammable gas detector is designed to detect the presence of flammable gases, such as methane, propane, and butane, in the surrounding environment. It utilizes gas sensors to measure the concentration of flammable gases and a microcontroller to process the sensor data. The detector is programmed to trigger an alarm and provide visual and auditory alerts when the gas concentration exceeds a predefined threshold, allowing users to take prompt actions to prevent potential fires.

How we built it:

We built our flammable gas detector using a combination of hardware and software components, using TinkerCAD, a popular online platform for virtual circuit design and simulation. We selected appropriate gas sensors with suitable sensitivity and accuracy for detecting specific flammable gases. We then designed and simulated the circuit using TinkerCAD's virtual components, including gas sensors, microcontrollers, and alarm systems. We programmed the microcontroller to read sensor data, process it, and control the alarm system based on predefined conditions.

Challenges we ran into:

During the development of the flammable gas detector, we encountered several challenges. One of the main challenges was simulating and testing the hardware and software components in a virtual environment using TinkerCAD. Debugging and troubleshooting issues in the virtual circuit required careful analysis and problem-solving skills. Another challenge was optimizing the performance of the gas sensors and the microcontroller to ensure accurate gas detection and reliable alarm triggering.

Accomplishments that we're proud of:

Despite the challenges, we successfully built a functional and reliable flammable gas detector in TinkerCAD. We were able to design and simulate a circuit that accurately detects flammable gases and triggers alarms in a virtual environment. We are proud of achieving the desired functionality and performance, including accurate gas detection, timely alarm triggering, and user-friendly interface for monitoring gas levels.

What we learned:

Throughout the development of the flammable gas detector project in TinkerCAD, we gained valuable experience in virtual circuit design, simulation, and troubleshooting. We learned about the selection and calibration of gas sensors, programming microcontrollers, and optimizing the performance of the detector. We also gained insights into the importance of thorough testing and validation in a virtual environment to ensure reliable and accurate performance of the gas detector.


Overall, the flammable gas detector project in hardware and software implementation using TinkerCAD was a challenging yet educational experience that enhanced our understanding of virtual circuit design, gas sensing technologies, and fire safety considerations. We are proud of our accomplishments and look forward to applying the knowledge gained to real-world applications.

What's next:

Still, a lot of work is left to make the project perfect. I would like to work on this step first. These are the tasks that are left:

  • Storing the responses in a Database for history creation and analytics by different researchers
  • Allow messaging not just through text but even chat apps like Whatsapp.
