Background: Before understanding H2S gas sensor, understand hydrogen sulfide gas. Hydrogen sulfide is a flammable, acidic gas in standard condition, colorless and has a rotten egg smell at low concentrations. If the concentration is very low, it will have a sulfur taste, which is highly toxic. When mixed with air, it can form an explosive […]

Background: The commonly used gas sensors in hVAC systems are O2 sensor and CO2 sensor. Heating, ventilation and air conditioning systems are primarily used to monitor and regulate the environmental conditions of all types of property and almost all vehicles on the road within certain limits. Although there may be obvious interrelationships between these three

Background: A large number of researches on hydrogen sensors have been carried out at home and abroad. At present, H2 sensor mainly fall into three categories: electrochemical, electrical and optical. In view of the wide use and insecurity of hydrogen in food hygiene, energy power, military and national defense, the concentration of hydrogen must be

Background: There are many types of liquid level sensor on the market, such as photoelectric, capacitive, float and so on. With the development of science and technology, the requirements for products will be higher and higher, and the relative requirements for liquid level sensor will be higher. And it is especially widely used in our

Summary: The portable weather station is a new type of online meteorological monitoring terminal integrating the online measurement of meteorological parameters. The equipment has the characteristics of small volume and integration. Easy to transport, carry and install, can adjust the position dynamically at any time. The appearance, working conditions, safety requirements and functional requirements of

Background: Aquatic organisms need oxygen in the water to sustain their activities. Oxygen in water is also called dissolved oxygen, and dissolved oxygen is one of the essential factors for aquaculture. Dissolved oxygen sensor can detect its concentration. When dissolved oxygen content in water is sufficient, organic matter can be decomposed quickly under the action

Summary: Ultrasonic wind speed and direction sensor is a meteorological measuring instrument which is developed and produced based on the principle of ultrasonic wave. Compared with other wind speed and direction sensors, ultrasonic wind speed and direction sensors have many advantages. Including strong anti-interference ability, high detection accuracy, widely used in the field of meteorological

Summary: With the development of intelligent agriculture in the Internet of things, many agricultural sensors appear in agricultural environmental monitoring, among which illumination sensor is a more important one. The sensor measures the intensity of light, which affects photosynthesis and, in turn, crop yields. In smart agricultural planting, the illumination sensor can detect the information

Background: Rainfall from the sky to the ground, the depth of the water layer that accumulates on the ground without evaporation, infiltration, or loss is called rainfall (in millimeters). The rainfall can be expressed intuitively. The amount of rainfall directly affects the growth of crops and people’s travel. However, too much or too little precipitation

Summary: Three cup wind speed sensor is mainly made of high quality aluminum alloy profiles. Surface electroplating spraying, with good anti-corrosion characteristics. It can effectively ensure that the instrument will not rust after long-term use, and ensure the accuracy of the collected information. It is an intelligent instrument with convenient use, excellent performance and high
