Industrial-grade MODBUS RS485 H2S Sensor - with Waterproof Aviation Connector

Product Description

Note

🌱The gas sensor needs to be calibrated after approximately six months of use to ensure its accuracy and reliability.

It measures the hydrogen sulfide concentration, air temperature, and humidity, making it widely applicable in industrial environmental sensing scenarios.

Features

🌱High Performance: High accuracy, fast response, fast return to zero, plug-and-play type.

🌱Multiple Uses: Ability to monitor hydrogen sulfide concentration, air temperature, and humidity.

🌱Ultralow-power: Smallest size and lowest power consumption sleep type design, lifetime up to 5 years or more.

🌱Combined with an intelligent algorithm, better environmental adaptability, more accurate detection, and stable zero point.

🌱New micro-circuit design, strong anti-electromagnetic interference.

Description

This H2S Sensor with Waterproof Aviation Connector measuresthe hydrogen sulfide concentration, air temperature, and humidityand is widely used in monitoring air quality. And it comes with auto temperature compensation, this sensor ensures the accuracy of measurements regardless of the environmental changes.

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 large 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 produces a lot of hydrogen sulfide, because the process of burning coal, fuel, and natural gases for making energy also produces a huge amount of hydrogen sulfide and faces the risk of improperly disposing of hydrogen sulfide.

RS485 H2S Sensor adopted an 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, and adopts a 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.

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, and the solid electrolyte conducts electron transfer, and generates a current signal as an output. The current signal can characterize the gas concentration.

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, and 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

SensorHub 4G 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).

Seeed also provides the SenseCAP Portal and SenseCAP Mate to help users better manage and check data remotely.
