The serious dust problem in closed coal yards significantly affects environmental quality and the health of workers. Traditional monitoring methods often have limitations such as low accuracy and susceptibility to interference. In contrast, laser dust sensors have advantages such as high precision, sensitivity, and rapid response, making them better suited for dust monitoring requirements. In closed coal yards, various production processes such as coal conveying, blending, screening, crushing, and...

TVOC, or Total Volatile Organic Compounds, refers to a collective term for various organic compounds that can evaporate into gases at room temperature. These compounds include alkanes, aromatics, olefins, halogens, esters, aldehydes, and more. Exposure to TVOC can irritate the eyes and respiratory system, causing harm to the liver, kidneys, brain, and nervous system. Among indoor air pollutants, TVOC is considered one of the more severe. It encompasses organic substances with a saturated vapor pressure...

Temperature and humidity, crucial metrics for measuring overall environmental quality, play a significant role in various fields such as agriculture, industry, buildings, offices, and server rooms. Temperature and humidity sensors, designed to measure these parameters, consist of humidity-sensitive and temperature-sensitive elements, converting these measurements into easily processed electrical signals. Despite the advancements in modern science and technology, the precision requirements for measurements...

A humidity sensor is an electronic device designed to measure and report the humidity and air temperature in the surrounding environment, whether it's in the air, soil, or enclosed spaces. Humidity measurements indicate the concentration of water vapor present in the air, providing measurement results in an appropriate electronic signal format. Additionally, they report relative humidity, which is the ratio of moisture to the maximum moisture content at a given temperature. Relative humidity...

Dust sensors are primarily employed to measure the concentration of particulate matter in various environments. As demands for improved living and working conditions rise, the hazards posed by industrial dust to human health have become increasingly evident. Construction sites, owing to large-scale operations, often generate airborne dust, serving as a principal contributor to urban dust pollution. Installing dust monitoring systems at construction sites can effectively enhance the dust environment....

In the current context of establishing standards for indoor air quality across various domains, the concentration of indoor CO2 is consistently mandated to remain below 1000 ppm. In normal circumstances, atmospheric CO2 concentration typically hovers around 400 ppm. Thus, the monitoring of air quality is inseparable from the application of high-precision carbon dioxide  sensors. Heating, ventilation, and air conditioning (HVAC) systems represent essential components for maintaining indoor comfort....

As global demand for clean energy rises, hydrogen gas has garnered substantial attention as an ideal energy source. However, its explosive nature and colorless, odorless properties pose significant safety challenges. The development of real-time hydrogen gas sensors to monitor its concentration and prevent accidents is therefore crucial.   Carbon nanotubes, a novel nanomaterial, have found extensive application in sensing due to their remarkable electrochemical properties and high surface area....

What is a Formaldehyde Sensor? The BA6208 formaldehyde sensor is specifically designed for the detection of formaldehyde gas (CH2O) based on the principle of electrochemical reaction. During the process of house decoration, a substantial amount of formaldehyde gas is often present. It is a colorless, irritating organic compound that has a stimulating effect on the eyes and nose, posing significant harm to human health. On October 27, 2017, formaldehyde was classified as a Group 1 carcinogen by the...

Types of Carbon Dioxide Sensors As people increasingly prioritize environmental and health concerns, the demand for fresh air systems, air conditioning, and other air purification devices is rising. Currently, the penetration rate of such air purification equipment in commercial buildings and residential spaces remains relatively low, indicating significant market potential in this field. In 2021, the global market sales of carbon dioxide (CO2) gas sensors reached $670 million, with an estimated...
