What Kind of Sensors Are Needed in Smart Agriculture?

Last Update Time: 2018-12-26 11:04:59

With the continuous advancement of modern society, the traditional agricultural production mode can no longer meet the needs of the development of modern civilization, and smart agriculture is gradually applied to the production of the whole world. Whether using satellites to communicate with each other in agricultural machinery or using IT technology to control the light and moisture of the greenhouse, the purpose is to improve the efficiency of agricultural production, change traditional agricultural production and management methods, and implement green production and improve the ecological environment.


Smart agriculture is a deep combination of Internet of Things technology and traditional agriculture. According to industry insiders, the most important of these is sensor technology. Through sensors, we can get rid of the natural factors such as weather and realize remote scientific monitoring in fields such as farmlands, greenhouses, aquatic products and livestock, effectively reducing human consumption. It is also possible to use scientific analysis to improve the ability to prevent agricultural disaster, resist risk and increase agricultural productivity. Agricultural sensors have brought traditional agricultural production to the path of smart agriculture, which is intelligent, automated and remotely controlled.


The agricultural greenhouses are often in a high temperature and high humidity environment. If the packaging technology is not closed, the core components and circuit boards of the sensor are easily damp and rusted, which will affect its accuracy and service life. Sensors installed in the field are also often exposed to wind and sun and chemical fertilizers and pesticides in the production process. Because plastics will lose their original performance under ultraviolet light, they will soon become embrittled and aging, seriously affecting the use life of sensors.


Therefore, it is very important to choose the right sensor in agricultural production. Agricultural sensors need to be waterproof, corrosion resistant, high temperature resistant, insect and fungus resistant, and the material requirements are very high. For example ceramic circuit board sensors, this sensor is resistant to sea salt corrosion and also meets the needs of marine aquaculture. Ceramic substrates are currently the most stable substrate materials with high thermal expansion coefficient and are widely used in agriculture.


In addition to the choice of materials, we must also pay attention to the stability of the sensor. When choosing an agricultural sensor, try to choose a sensor that is free of calibration or with long calibration period. Agricultural sensors have low accuracy requirements and can meet daily production needs. However, due to the special nature of the environment, most of the agricultural projects are carried out in the field. The calibration operation is very inconvenient and the labor cost is also very high. Therefore, the stability of the sensor data is very high, and the low-drift, calibration-free sensor is tried as far as possible. However, some water quality sensors may not be able to be corrected, and try to select a sensor with a long calibration period to reduce labor costs.
