Application of Sensors in Precision Agriculture

Agricultural engineering is associated with technologies that allow the use of newagricultural tools. In modern agriculture, instead of determining the amount of seedneeded to produce the product, it is possible to identify the sensors that can determine theamount of seed needed for the equipment used for crop cultivation. The sensor convertsphysical quantities such as pressure, heat, humidity, etc. into analogue or digital electricalquantities. In fact, the sensor is an electrical device that measures physical or chemicalchanges and converts it into an electrical signal. Optical sensors measure the amount oflight that is diffusely reflected from the soil after radiation containing all the pertainingfrequencies illuminates it. Sensors can be placed on vehicles or aerial platforms such asdrones or even satellites. Biosensor technology is a powerful alternative to conventionalanalytical techniques, harnessing the specificity and sensitivity of biological systems insmall, low cost devices. Increasing performance, reducing costs and improving theenvironment are among the most important benefits of using this technology inagriculture.
