Overview Rain and snow sensors are mainly used to detect whether there is rain or snow in nature. This sensor adopts AC impedance measurement method. The electrode has a long service life. There will be no oxidation problems. The rain and snow sensor can be widely used in the environment, greenhouses, breeding, construction, buildings, etc. […]

Water quality monitoring environment Water quality environmental monitoring is the basis for rational use of water resources and protection of water resources. It is a strategic element directly related to people’s health. It is an important measure to implement sustainable development. Global water pollution is getting worse. Environmental monitoring of water quality is also receiving

Overview Ammonia easily liquefies into a colorless liquid. It can be liquefied under pressure at room temperature (critical temperature is 132.4℃, critical pressure is 11.2MPa, which is 112.2 atmospheres). Boiling point -33.5°C. It is also easy to solidify into a snow-like solid. Melting point -77.75°C. Soluble in water, ethanol and ether. It will decompose into

Background In the greenhouse environment. Temperature and humidity are very important climatic conditions. Too high or low temperature and humidity are not conducive to the growth of crops. Meteorological stations can continuously monitor and collect information on agro-meteorological environmental factors such as soil, moisture, light, and heat that are closely related to vegetation and crop

What is an automatic weather station: An automatic weather station is a device that can automatically observe and store weather observation data. It is mainly composed of meteorological sensors, collectors, and communication interfaces. System power and other components. As the value of meteorological elements changes. The power output from the sensing element of each sensor

Summary: Sulfur dioxide (SO2) is a colorless transparent gas, is a toxic gas with a pungent odor. Can accelerate the corrosion process of most metals.In the presence of PM2.5, sulfite is dissolved in the solution, under which conditions sulfite is oxidized and then converted to sulfuric acid. In the traditional sense, this is the origin

Portable dissolved oxygen meter introduction: Portable dissolved oxygen meter is an instrument for measuring oxygen content in water made on the basis of electrochemical principle. The electrochemistry principle is that a REDOX reaction will occur at two different metal electrodes in an oxygen-containing electrolyte solution to be measured. The resulting diffusion current and the oxygen

Summary: Water resource is one of the indispensable resources for the development of human society and economy. To ensure the development of social economy and People’s Daily life and production. The water resource crisis in the current human society has directly limited the economic development. And affect the normal life of human beings, so it

Summary: Many people in the field need to add water or drainage operations, the use of floating ball level meter to control the level. According to the reason, is in the appropriate. But because the actual situation will appear on the spot, the installation is not very convenient. Like the top of the container is

What is the meaning of PH in water? PH is a measure of the acidity or alkalinity of water. It can be calculated according to the hydrogen ion concentration and the corresponding calculation formula. PH value is a routine and important water quality monitoring parameter. The acidity or alkalinity of water can be detected and
