The S-H2S-01 is an electrochemical detection of solid polymers with a revolutionary innovative technic in electrochemical detection area with widely applications in farming area, industry area and meteorological monitoring.
- Multiple Uses: Ability to monitor hydrogen sulfide concentration, air temperature, and humidity.
- Highly resist of Disturbance: Toleration for extreme temperature and exposure to high levels of ammonia gas.
- Application for a variety of areas: Livestock farming, gas leaking detection for heavy industry and atmospheric environmental gas detection, etc.
- Customer-friendly: Easy to set up and support adjustment for different uses.
Hydrogen sulfide is the most common source of where the stinky smell came from in our daily life and it has a tremendous effect on our healthy life. Different levels of hydrogen sulfide make a different impact, for example, a small number of hydrogen sulfide only make you suffer from a bad smell. However, when one area concentrates a big amount of large hydrogen sulfide, it will hurt your olfactory system and poisoning will happen.
There are different kinds of methods of producing hydrogen sulfide whether by humans or by nature. The excretion produced by the livestock farming industry, in the process or reserve excretion by livestock and recycling of the excretion will produce an enormous amount of ammonia gas. Heavy industry using energy also producing a lot of hydrogen sulfide, because the process of burning coal, fuel, and natural gases for making energy also producing a huge amount of hydrogen sulfide and faces the risk of improperly disposing of hydrogen sulfide.
RS485 H2S Sensor S-H2S-01adopted import sensor chip from Germany with the ability to monitor hydrogen sulfide concentration, air temperature, and humidity at the same time. The sensor transmits data with the help of the RS485 Modbus RTU protocol. The sensor contains excellent features as it can respond to gas or environment with high speed and sensibility, has the ability to tolerate disturbance, adopts compensation algorithm and adjustable standards, all of that to assure the accuracy of the sensor. This equipment was powered by 5V DC, able to support most of the sensors in the market. Equipment can be easily integrated into most of the system without a complex setup procedure.
Solid polymer electrochemical technology is a revolutionary innovation in the field of electrochemical detection. This technology is based on the principle of electrochemical catalytic reaction triggered by different target gas leading to sending out a different electrical signal that is directly proportional to the gas concentration. The sensor module is composed of three catalytic electrodes, a solid electrolyte, and gas diffusion holes. The gas reaches the working electrode of the sensor through the diffusion holes, an electrochemical redox reaction occurs on the porous micro-surface of the electrode, the solid electrolyte conducts electron transfer, and generates a current signal as an output. The current signal can characterize the gas concentration.
Recommendation for SensorHUB
Sensor Hub Data Logger is an easy-to-deploy 4G cellular station. It uses the MODBUS-RTU RS485 protocol to communicate with sensors and can collect various sensor data simultaneously.
Sensor Hub consists of 4 RS485 data channels. With extension hubs / RS485 splitters, it can connect with a maximum of 32 sensors at one time. The data is collected and sent to the cloud (either to the SenseCAP server or the client's private server) via 4G/3G/2G (as shown below).
Designed with industry standards and IP66 rated, Sensor Hub is suitable for outdoor and harsh environments, resistant to UV, rain, and dust, etc. GNSS is embedded for location tracking.
Sensor Hub is also equipped with 10MB onboard memory, to store more than 700,000 measurements locally in case of a bad connection.
