Which devices can detect and identify combustible gases?
Posted On August 4, 2021
A smart voice-recognition device developed by researchers at the University of Wisconsin at Madison may be able to identify and warn about harmful compounds that can emit deadly and flammable fumes.
The researchers found that their device is capable of detecting and predicting the presence of volatile organic compounds (VOCs) in air.
The devices use electrochemical detection, which uses light and electricity to measure the concentration of compounds in air, according to a press release.
The results, published in the journal Proceedings of the National Academy of Sciences, are the result of an experiment conducted with a smartphone.
The device’s device was powered off by a small circuit board.
A smartphone connected to the device was then turned on and the device recorded the time the phone was on and when the device turned on.
It then calculated how long the device had been on and calculated how much power was consumed by the device.
After analyzing the time it took to get to the end of the recording, the device detected the presence and duration of the volatile organic compound (VOG) detected in the air.
This detection was able to predict the presence in about two minutes.
It is possible that the device will be able learn more about VOCs in air in the future, but the results are promising.
The research team is now working on developing a smart voice recognition device that can be programmed to detect and respond to a variety of dangerous VOC-containing gases.
Researchers are also exploring the possibility of making this device work in conjunction with an external detector, such as a smoke detector, and using the device to detect smoke.
