Traditional stethoscopes, while a staple in medical diagnostics, often fall short in certain areas. Their sound output is weak, they provide limited noise isolation, and they lack frequency adjustment capabilities. Addressing these limitations, Isweek introduces the CM-01B high-sensitivity piezo film sensor as an ideal solution, revolutionizing conventional stethoscope applications with…
In 2015, vehicles driven by H2 fuel cells stepped into the first state of commercialization. Toyota Mirai has been in the market of America and Europe, and is planning to enter China later. In China, performance of fuel cell vehicles can basically meet the requirements of operation, so they have…
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 today’s interconnected world, where smart homes and IoT are transforming lifestyles, maintaining a comfortable and healthy living environment has become a priority. Environmental monitoring devices, including temperature and humidity sensors and PM2.5 sensors, play a critical role in improving air quality and enhancing home automation systems. Addressing Air Quality…
PM2.5 sensors play a critical role in monitoring air quality, particularly in environments affected by pollution. Their working principle is rooted in light scattering: particles in the air scatter light, and by measuring the attenuation of this light, the concentration of airborne particles can be calculated. Below, we explore several…
Integrated temperature and humidity sensors of small size and high accuracy are widely applied in cellphones, communication, HVAC, medical care, environment monitoring, home appliances and control panels. Here we ISWeek would like to compare the two best sellers in the market – HTU21D and SHT21- from aspects of their cost efficiency,…
Cigar enthusiasts understand that proper storage conditions are crucial to maintaining the flavor, aroma, and quality of cigars. While the quality of a cigar depends on the tobacco leaves, its preservation method plays an even more significant role. Newly purchased cigars often lack the refined taste that develops over time….
In today’s world, smart home technology is revolutionizing safety and convenience. Gas sensors play a crucial role in protecting households from CO poisoning and combustible gas leaks, offering real-time monitoring and automatic alerts. Why Smart Homes Need CO & Combustible Gas Sensors? Carbon monoxide (CO) and combustible gas leaks pose…
Municipal sewers, sewage conduits, bilge wells, and septic tanks transport both sanitary and industrial wastewater in urban areas. In these relatively sealed spaces, organic and inorganic matter in wastewater is decomposed by microbial action under anaerobic conditions, generating toxic and combustible gases. Without proper management and supervision, these gases can…
With rapid urbanization, utility tunnels play a crucial role in maintaining smooth city operations by consolidating pipelines and reducing construction-related accidents. To ensure safety and efficiency, sensor monitoring systems are deployed throughout utility tunnels to provide real-time data on key parameters. Real-Time Environmental Monitoring Sensors are strategically installed at set…
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 cooling systems such as central air-conditioning, heat pump air-conditioning, household air-conditioners, and other small-sized cooling equipment. The fluid circulates through the system, exchanging energy with the outside via changes in its thermodynamic states to provide cooling. Freon, the high-performing refrigerant introduced by DuPont…
