Product description: Fermion - H2S hydrogen sulfide sensor - MEMS - 0.5-50 ppm - DFRobot SEN0568
A sensor manufactured by DFRobot, designed to measure the concentration of hydrogen sulfide H2S in air. The measurement range is from 0.5 ppm to 50 ppm . Moreover, the sensor is made using MEMS technology, thanks to which it has low energy consumption, its current consumption does not exceed 20 mA , and its dimensions are 13 x 13 x 2.5 mm. The module is used for underground detection of hydrogen sulfide, as well as for industrial detection of this gas in large-scale facilities.

Hydrogen sulfide is dangerous even in small amounts, it attacks mucous membranes and nervous tissues.
How to detect hydrogen sulfide? What does hydrogen sulfide smell like?
Hydrogen sulfide H2S is a gas that is not so easy to detect. Only at high concentrations will our sense of smell react to its presence, because its smell resembles the stench of rotten eggs. It is dangerous even in small amounts - exposure to low concentrations of H2S may lead to irritation of the eyes and respiratory tract, while long-term or intense exposure to higher concentrations may result in more serious health problems, including damage to the nervous system.
Hydrogen sulfide is naturally produced as a result of the decomposition of organic matter by bacteria in anaerobic conditions, which occurs, for example, in swamps, at the bottom of reservoirs, in mines, and in sewage pipes. Industrially, H2S is a by-product in many processes such as petroleum refining, gas purification, pulp and paper production, as well as in food industry processes related to protein processing. Due to its properties, hydrogen sulfide is also used in the chemical industry, including: for the production of sulfur and sulfuric acid and as a component of some decontamination processes.
Suggested use of the sensor

Precautions during use
- Before using the sensor, remove the protective film from it.
- Avoid using the sensor in an environment where it will be exposed to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, among others).
- Protect the sensor from contamination with alkalis, alkali metal salts and halogens.
- Avoid long-term exposure of the tile to unfavorable environmental conditions (such as high temperatures, high humidity, high pollution).
- Do not expose the module to water.
- Do not expose the module to vibrations, impacts or falls from height.
- Do not test the module on systems that involve personal security concerns.
