     Wireless LoRaWAN H2S Environmental Sensor

xiamen ZoneWu LoRaWAN H2S gas sensor is a new type of wireless sensor made with LoRaTM spread spectrum modulation technology, which is specifically used to detect hydrogen sulfide gas. 

xiamen ZoneWu LoRaWAN Gas Sensor H2S Sensor Features:

 

This device has a comprehensive function, can collect data, and also stare at the environment conditions in real time, and can transmit data to the outside world, which is a "versatile hand."

 

It contains hydrogen sulfide (H2S) sensors, as well as temperature and humidity sensors, which can sense changes in the surrounding environment in all directions.

 

It uses three-electrode electrochemical gas sensor and high-performance microprocessor to detect hydrogen sulfide gas in the environment, and at the same time uses the built-in temperature sensor to compensate for the temperature, ensuring that the gas concentration measured is accurate.

 

If something is wrong in the field environment, it can report data exceptions immediately, and will proactively report the exceptions as soon as the numerical limits set in advance are reached.

 

There are especially many applications, such as hydrogen battery processing, medical applications, chemical industry and steel industry, where it can be seen to play a role.

 

complete functions, precise detection, rapid response, can adapt to the needs of different industries, and provide strong guarantees for safety and production in various fields.

Common knowledge of  H2S

 

How does a hydrogen sulfide sensor detect hydrogen sulfide gas

Hydrogen sulfide sensors usually use electrochemical principles, utilizing three electrodes to electrochemical gas sensors, When hydrogen sulfide gas enters the sensor, an oxidation reduction reaction occurs on the electrode, thereby producing an electrical signal proportional to the concentration of hydrogen sulfur sulfide. The concentration of the hydrogen sulfate is determined by the detection and treatment of the electrical signal. 

 

 

Does the hydrogen sulfide sensor need to be calibrated regularly

Need. In order to ensure the accuracy and reliability of sensor measurement, it is usually necessary to regularly calibrate the hydrogen sulfide sensor, and the calibration cycle is generally six months to one year, which can be adjusted appropriately according to factors such as the use environment and frequency. 

 

What is the detection range of the hydrogen sulfide sensor

The detection range of different models of hydrogen sulfide sensor is different, generally the common detection range is between 0-100ppm (one millionth) to 0-10,000ppm, and the sensor with suitable detection range can be selected according to the specific use scene and demand.
