Specialists from MIET have developed sensors that can accurately detect ammonia in the air. We tell you more about why this is important.
The devices are capable of recognizing one molecule of ammonia among five billion molecules of air, which makes them useful for monitoring the atmosphere and in industries such as agriculture, pharmaceuticals, and chemistry.
Ammonia (NH3) is a gas with a pungent odor that is used in industry. High concentrations of ammonia can cause health problems, such as irritation of the eyes and respiratory tract. However, a person can only smell it at high concentrations, while low levels can be dangerous but unnoticeable.
The developed sensors use carbon nanotubes, which allows them to operate at room temperature, unlike other technologies that require heating. This makes the devices more convenient and expands their application.
The sensitivity of the new sensors is more than ten thousand times higher than the capabilities of the human sense of smell, which brings them closer to the ability of animals, such as dogs, to recognize very low concentrations of gas.
