Summary: In the study of plant physiology, the determination of plant photosynthesis is one of the important research work. It is generally measured by measuring the value of illuminance and photosynthetically active radiation, and the measurement of illuminance and photosynthetically active radiation requires a light sensor and photosynthetically active radiation sensor. To understand the difference […]

Background: In ancient times, weather played an important role in deciding victory or defeat in war. With the progress of science and technology, our life is gradually inseparable from weather, and our life is affected by weather everywhere. Anyone who knows about weather stations knows that there are many kinds of weather stations. Outdoor weather

Summary: The Internet of Things (IoT) is a network that connects any object to the Internet for information exchange and communication to realize intelligent identification, location, tracking, monitoring and management. In short, the Internet of Things is the Internet of things. Intelligent sensor as three hierarchy iot perception layer, one of the important part of

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
