Summary: Fish and shellfish need oxygen to live, grow and reproduce. If fish die or do not grow large enough to reproduce, low dissolved oxygen levels can lead to fish farming failures. Dissolved oxygen sensor can be used to measure dissolved oxygen levels in the water. Why does dissolved oxygen fluctuate? Several factors affect the […]

Background: In People’s Daily life, we can know the change of wind speed and weather by meteorological monitoring, and we can use ultrasonic wind speed sensor to detect wind speed. Of course, there is also the change of wind direction. For the measurement of wind direction, wind direction instrument or wind direction sensor equipment is

Background: In recent years, with the rapid development of science and technology, electronic and mechanical products used in industry and life are increasingly automated. For example, in the chemical food, medicine and other industries in the production of liquid level sensor, liquid level sensor and photoelectric, floating ball type, capacitive, electrode type and other types.

Background: Carbon monoxide is one of the most common colorless, odorless, odorless, tasteless and non-irritating harmful gases, which can be detected by CO gas detector. When gas burns, if the oxygen in the air is insufficient and combustion is insufficient, carbon monoxide poisoning, commonly known as gas poisoning, will occur. Carbon monoxide inhalation can cause

Background: With the progress of science and technology, people gradually deepen the understanding of solar radiation, through the total solar radiation sensor. In order to improve the utilization rate of total solar radiation, make it play a greater role. In industry, total solar radiation is monitored by using total solar radiation sensor. And according to

Background: An wind speed sensor is a device used to measure wind speed. Compact and light in shape, easy to carry and assemble. According to the working principle, it can be roughly divided into mechanical anemometer and ultrasonic anemometer. The shell is made of high quality aluminum alloy profile or polycarbonate composite material. Rain proof,

Background: Portable small weather station belongs to a small weather station, easy to carry. Portable small weather station mainly consists of weather sensor, collector, transmission module, support and other parts. With the rapid development of agricultural planting in recent years. Many large agricultural planting areas have introduced small weather stations to monitor meteorological changes anytime

Background: The concentration of chlorophyll represents the concentration of algae in the water, which can be detected by a chlorophyll detector. The concentration of algae can reflect the degree of eutrophication, that is, the degree of water pollution. Therefore, chlorophyll level is an important indicator of water environment, and chlorophyll is closely related to ammonia

Background: Nitrogen dioxide gas concentration can be measured by electrochemical NO2 gas sensor. On the one hand, under certain conditions, nitrogen dioxide can combine with hydrocarbons in the air to form photochemical smog. Damage the air quality of the atmosphere environment, seriously harm people’s health, so that people rely on the air environment is polluted.

Background: School is very important, it concerns the future development of the whole country. Carbon dioxide gas transmitter will also be used. Schools may be built in distant places, or in busy city centers. No matter where they are, schools will face an important problem, that is, air quality. Schools are places where large crowds
