Introduction An NDIR CO2 sensor (Non-Dispersive Infrared CO2 Sensor) is a device used to detect and measure the concentration of carbon dioxide (CO2) in the air. It operates based on the principle that CO2 molecules absorb infrared (IR) light at a specific wavelength. This guide will share the NDIR CO2…
Introduction Acetone, a colorless, volatile liquid, is a common solvent found in various household and industrial products. Known for its distinctive smell, it is widely used in industries ranging from pharmaceuticals to cosmetics. In the medical field, acetone’s presence in the human body can indicate various metabolic conditions, making its…
Introduction An electrochemical gas sensor operates by interacting with the target gas and producing an electrical signal proportional to the gas concentration. These industrial sensors are known for their high sensitivity, excellent selectivity, and linear output at low concentrations. Moreover, they function effectively in challenging conditions, including low and high…
Argon arc welding, a revolutionary technique in modern metallurgy, leverages argon gas to protect and bond metals during welding. The MTCS2601 thermal conductivity sensor ensures accurate monitoring and control of argon concentration, optimizing the welding process and enhancing weld quality. Understanding Argon Arc Welding Argon arc welding uses argon, an…
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…
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…
