Technical innovation in agriculture is of extreme importance, in particular to address global challenges such as population growth, climate change and the limited availability of important plant nutrients such as phosphorus and potassium. Sensors applied to agricultural production could play a fundamental role for this purpose and research into agricultural applications has been ongoing for largely a decade [1]. Relevance of the paper is to develop a system for smart agriculture necessary for the development of agricultural production in our country in a similar manner to the European Union. Agriculture and allied activities play a vital role in a country's economic prosperity. The conventional methods in agricultural practices have become grossly inadequate to cater to the increasing needs. Thus it has become imperative to adopt novel technologies to raise agricultural standards. This paper proposes a system in a limited, enclosed area wherein different sensors are strategically positioned to measure parameters such as moisture content, temperature, pressure, light intensity and pH of the soil [5].
In practice, different types of equipment are known for scanning soil properties using optoelectronic technologies. These include drone-based technology and surface or deep-soil scanning technology in dynamic or static mode. The surface scanning technology developed by Veris Technologies in the USA is based on soil scanning while moving using a mobile platform that penetrates the soil to a depth of 5-10 cm [1]. The most commonly used static technology is based on the collection of soil data using a mobile platform that moves from place to place. Once the predetermined location is reached, the platform penetrates the soil to various depths from which it takes samples to which the spectra are determined. The technical problem solved by the proposed solution is the creation of an intelligent electronic control and command device (IECCD) of mobile optoelectronic platforms for scanning soil properties [2]. It has a structure that allows the functions required for the platform to be realized, based on a series of inputs, outputs and communication ports.
