Poisonous Gas Detection and Alarming Device
Abstract

Exposure to toxic gases such as hydrogen sulfide, mercury vapor, and carbon monoxide—even in small amounts—can lead to poisoning and long-term health issues. These gases can accumulate to dangerous and potentially fatal concentrations in various environments, including industrial processes involving flammable or poisonous gases, as well as in sewage systems, septic tanks, manholes, and dumping grounds where such gases are commonly generated. To mitigate these risks, industrial plants typically use gas detection systems that include multiple sensors distributed throughout the facility, all connected to a central station. When a sensor detects a hazardous gas level exceeding a set threshold, an alarm is triggered at the central station to alert personnel. In response to the limitations of existing systems, the present invention introduces a portable device designed to detect hazardous and poisonous gases. This gas detection and alarming device includes multiple sensors, several alarm mechanisms, and a processor. Compact and user-friendly, the device acts as a crucial safety tool, providing timely alerts in the event of toxic gas leaks or hazardous conditions, thereby enabling users to evacuate the area promptly.

Problem Statement

Industrial plants that involve processes emitting hazardous gases rely on gas detection systems to ensure safety. These systems consist of gas sensors distributed across the plant, all connected to a central station that monitors the sensor signals. When a sensor detects a dangerous concentration of gas, it triggers an alarm at the central station to alert personnel. However, conventional industrial gas detection systems are often prohibitively expensive and feature central stations with limited upgradability due to their bulky hardware. This limitation restricts their usability and scalability, resulting in many workers being routinely exposed to potentially fatal levels of toxic gases. Therefore, there is a significant need for a more efficient, cost-effective, and portable gas detector that can promptly detect hazardous gases, providing sufficient warning time for safe evacuation in emergency situations.

Uniqueness of the Solution
  • Power Supply: The device is powered by a rechargeable Lithium-ion battery, which supplies energy to the Arduino UNO board and all attached components. The battery can be charged using a 9V barrel AC-to-DC charger or a USB connecting cable. 
  • Programming and Calibration: The processor uses open-source Arduino IDE software to set threshold levels and calibrate gas detection based on varying sensor resistance levels. This allows the device to accurately respond to different concentrations of hazardous gases. 
  • Update Capability: A built-in data port allows connection via USB cable, enabling users to update the processor program whenever necessary. 
  • Portability and Ease of Use: The device is compact, easy to carry, and simple to operate. It reliably detects hazardous and toxic gases in the atmosphere, providing users with adequate warning time to escape in emergency situations.
