Maintaining good indoor air quality is critical for health and productivity. Elevated carbon dioxide (CO2) levels in enclosed spaces can lead to discomfort, reduced focus, and long-term health risks. While pollutants like PM2.5 often take the spotlight, CO2 is an equally significant contributor to poor indoor air quality. Why Monitor…
Introduction to Vacuum Valves and Their Role Vacuum valves are indispensable components in vacuum systems, tasked with directing airflow, regulating mass flow, and connecting or isolating vacuum system pipelines. To ensure efficiency and reliability, these valves rely on precise control mechanisms, such as vacuum electromagnetic valves, which leverage AC or…
Proper storage of vegetables and fruits is critical for preserving their freshness, nutritional value, and marketability. However, their perishability and seasonal characteristics make storage and transportation challenging. Many fruits and vegetables have high water content and centralized harvest periods, leading to rapid spoilage if not stored properly. To combat these…
Introduction A Zirconia Oxygen Sensor, often referred to simply as an oxygen sensor or O2 sensor, is a device utilized in automotive and industrial applications to measure the proportion of oxygen in exhaust gases or other environments. It is vital for ensuring the correct air-fuel ratio in internal combustion engines, which…
What is the problem that needs to be solved? Building Management Systems (BMS), Demand-Controlled Ventilation (DCV) systems and Indoor Air Quality (IAQ) equipment often require installation of wirelessly-connected, battery-powered CO2 sensor devices in environments where mains power is not easily accessible or where its provision is not economically viable; such…
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 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…
