Gas detection techniques have a fascinating history, dating back to the 19th century when canaries served as early warning systems for toxic gases in coal mines. When coal emerged as the Industrial ...

Here is a gas leak detector circuit that detects the leakage of LPG gas and alerts the user through audio-visual indications. The circuit operates off a 9V PP3 battery. Zener diode ZD1 is used to ...

It is well known that dogs have a better sense of smell than humans. For years, researchers have been trying to develop an artificial detector that is just as good as a canine's nose. Now, one group ...

Carbon Monoxide CO cannot be seen, smelled, or tasted. In large quantities, it may kill within minutes. Incomplete combustion produces carbon monoxide, a gaseous byproduct that may leak from faulty or ...

Four of your team members are hard at work, side by side at your facility. Each is wearing a brand-new gas detector that was calibrated and bump tested only a few hours ago. The problem is that two of ...

The use of gas sensors in detecting, monitoring, and evaluating combustion-related toxic and exhaust gases has attracted much interest. This technique finds practical application at both industrial ...

{mosimage} A gaseous mixture sample passes through a membrane into a measurement cell, which contains an optical light source and a microphone. Incident light modulated at a specific frequency is ...
