Abstract:This paper presents a review of the state of the art about the production and technological development of IoT appliances, based on the use of programmable devices (microcontrollers, microprocessors and DSP digital signal processors) in the agro-industrial sector of the department of Boyacá, in Colombia, as mainly in applications for smallholder agricultural production. A brief description of the issues faced by the agro-industrial sector of the department is addressed here, taking into account some considerations established by the Strategic Plan of Science, Technology and Innovation “PEDCTI Boyacá 2022”. That is, science, technology and innovation STI at the service of regional development, addressing only milk, fruit and horticultural sectors, since they are the main agro-industrial chains in the region. Likewise, a procedure for searching and gathering information on IoT devices based on microcontrollers has been performed from well-known databases. Finally, a comprehensive review of STI capabilities is carried out in the universities of the department of Boyacá, which reveals a low technological production focused on agriculture, and a scarce amount of developments proposed mainly for scale or prototype deployment, without a real payoff in the sector |
