Product Description

H2+2MPI


WxS 8702E-027

H2+2MPI


Overview

The WxS 8700 is a wireless gas sensing platform based on LoRa technology operating at license free spectrum (ISM), enabling both public and private IoT network deployments by service providers, municipality governments, enterprises. It’s deployed in star topology with very high density, particularly suited for industrial and enterprise IoT applications such as

1)      Industrial campus safety

2)      Smart and Safety

3)      Environmental Monitoring

4)      Subway security and safety

5)      Hospitality safety

6)      Residential complex, shopping center, CBD safety

 Polysense iView is a cloud IoT network management and sensing data analytic platform, supporting Polysense sensor end nodes, such as WxS 8800 and WxS 8700, and 3rd party sensor nodes and definition of new sensor data types. It provides flexible sensor data format conversion, data import and export; charting, data analytic, integrated map, zone and priority based alert management, SMS text and email notification, and open API for 3rd party integration.

The harm of H2

Although hydrogen is avirulent, it is inert to human body on physiology, but if the hydrogen content in air increases, will cause lack of oxygen sex to asphyxiate.As with all cryogenic liquids, direct contact with liquid hydrogen can cause frostbite.

 

The Sample Applications

 Gas, dust, and particulate matters are today present everywhere in our daily lives – in our breathing atmosphere, in our homes, in our working environment, in our vehicles; there is no escape of such seemingly invisible stuff. 

Some of them are unharmful, even necessary, such as O2. However, many are dangerous – flammable to cause fire, explosive to cause major accidents, poisonous to cause cancers, major elements of environmental pollutions, or bad living environment with bad odor. They can be generated in many industrial processes, from vehicles, or just gas leaks.

Therefore, it is becoming increasingly critical to be able to detect and monitor the presence and density of such type of gases, dust and particulate matters, for the safety of the society and the health of human beings, making sure the density level does not rise or cross the dangerous threshold level or report timely to avoid major accidents by advanced warnings.

 

Applications

Description

Industrial campus safety

Many industrial operations, as part of the chemical process, generate  certain types of gases which may be harmful to workers, pollute the air, or  even causing fire or explosion under certain conditions (temperature and  pressure). WxS 8700 can be installed to detect and monitor virtually all  dangerous gases while assessing the environmental condition (temperature and  pressure)

Residential Complex, hospitality hotels, shopping center, CBD Safety

Keeping the shopping center, CBD and complex safe and pleasant is one of  the key factors to attract customers.   WxS 8800 can be installed at strategic locations, such as public  square, hallway, restroom to detect and monitor fire and smoke (Temperature  and CO), bad odor (NH3, O3), and dangerous gases (such as CH4).

Subway security and safety

Crowded spaces such as subway are always potentially dangerous for  accidental gas leaks, fire, or terrorism attacks. WxS 8700 can be installed  at strategic locations to monitor the presence and arise of such dangerous  gas elements in combination with temperature monitoring

Environment Monitoring

Air quality (AQI) is now a major measurement of quality of life in any  city. A holistic view of the air quality consists of a number of  measurements, including CO, CO2, O3, NO2, and PM 1/2.5/10, street noise  level. WxS 8700 enables the sampling, collection, edge processing,  transmission of all these critical parameters

Smart Home

You often go back home multiple times to double check that the  appliances in kitchen is turned off when you leave home to work or go on a  vacation. You are concerned about gas leaks and fire. WxS 8700 can monitor  temperature, CO, CH4, nature gas – while you are away and alert you if  anything abnormal is detected
