Natural gas is a kind of fossil fuel in gas state whose major component is alkane. Different from other fuel, it generates no waste water or residue in combustion. Comparing with coal gas, it’s obviously a sort of clean energy source, since that it produces few harmful materials but only…
In this era of IoT, people pursuing comfortable lives are paying more attention to health care and environmental quality. Smart city and smart homes appear consequently. Among all kinds of devices, environment monitoring devices used in smart homes are most popular, thus PM2.5 sensors and temperature and humidity sensors are…
The working principle of PM2.5 sensors is based on light scattering. When being exposed to light, particles and molecules will absorb part of the energy, and scatter part of the light. When a light beam goes parallel into the particle field to be measured, the light is affected by scattering and…
Integrated temp&humidity sensors of small size and high accuracy are widely applied in cellphones, communication, HVAC, medical care, environment monitoring, home appliance and control panels. Here we ISWeek would like to make a comparison between the two best sellers in the market – HTU21D and SHT21- from aspects of their cost…
Cigar lovers are often concerning about the conditions of their cigar, since that good cigar can provide a joyful experience. The quality of cigars partially depend on its tobacco leaves, but mainly on its treatment. The newly bought cigars taste no better than immature fruits, so they need to be…
Nowadays, sensors have been integrated into everywhere of our life. They analyze users` daily behaviors and enrich users` interaction channels with their circumstances. Some smart sensors, like motion sensors and temperature & humidity sensors, enhance the safety and convenience of our life significantly. Sensors are essential in designs and solutions…
Municipal sewers, sewage conduits, bilge wells and septic-tanks are containing and conveying sanitary and industrial sewage in urban areas. However, being sealed in such a relatively closed space, organic and inorganic matters in waste water can be resolved by microbial actions under anaerobic conditions to generate toxic and combustible gases….
With the acceleration of modern urbanization, the city pipe network is burdening increasingly heavier pressure to keep the city’s smooth operation. The expansion, transformation and maintenance of the pipelines always bring people lots of inconvenience, and cause large economic waste. Every year loss of hundred billions yuan is directly or…
Beer has been a popular drink among all. Especially in summer, a beer with BBQ can be the best refreshment. For now there are many breweries producing various kinds of bear, but also producing problems of waste water treatment. The waste water which contains large amounts of organic pollutants, are…
Refrigerating fluid is the working medium in a cooling system like central air-conditioning, heat pump air-conditioning, household air-conditioners and other small-sized cooling equipment. The fluid circulates in the system and exchange energy with the outside via changes of its thermodynamic states, so as to cool the system down. Freon, the…
Internet of Things(IoT) is actually a large information system based on computer Internet. With RFID and wireless data communication technology, interconnection between software on sensing layer and application layer is built, and a grand information network is thus formed. With the presence of IoT, wireless connections is creating a network that…
Scrubbing solution is the solution to be added in washing section during fractional extraction process used for eliminating impurities and fission fragments from load organic phase. Various scrubbing solutions are used for different kinds of demands. ISWeek would like to demonstrate how liquid level of scrubbing solutions in washing equipment can…
