Cold chain logistics, as the name suggests, means that some sort of cold temperature is always maintained during transport. There are many methods of cold chain transport - land, water, rail and air - but because of this, the technology behind trying to achieve a constant temperature involves quick loading, mobile refrigeration, the manufacture of insulated containers and much more. Cold chain...

In recent years, air pollution has become more and more serious, and people's awareness of environmental protection has gradually increased. Haze has then attracted widespread attention, and most people are aware of the causes of PM2.5 exceedance: motor vehicle emissions, industrial pollution, coal-fired pollution, construction dust, and external pollution. Another important source of pollution...

The amount of evaporation, the process of water changing from liquid or solid state to gaseous state and escaping into the atmosphere is called evaporation. Evaporation is the amount of water dispersed into the air by evaporation in a certain period of time, usually expressed in millimeters of the thickness of the evaporated water layer, the evaporation of water surface or soil water,...

With the increasing update of modern science and technology and the restructuring of agricultural industrialization, the level of modern agriculture technology is increasing. Traditional agriculture has been eliminated due to outdated equipment, and now modern commercial type agriculture armed with modern science and technology and equipment, in which sensors play an irreplaceable and effective...

At present, most environmental parameters in smart agriculture such as temperature, humidity, CO2 concentration, soil temperature, foliar humidity and light level in greenhouses are collected in real time by physical sensors, among which temperature and humidity sensors are the most widely used type of sensors in smart agriculture, which are widely used for temperature and humidity monitoring...

In information-based agriculture, we often need to obtain information on environmental temperature, humidity, light intensity, gas concentration, etc. How to effectively obtain this information is a key issue in achieving smart agriculture, and sensor technology provides technical support to solve this problem. In the field of modern science and technology, all kinds of material information...
