Desarrollo de un equipo de monitoreo inalámbrico de sensores alimentado mediante celdas de combustible microbianas para el Centro de Energías Alternativas y Ambiente de la ESPOCH.

Abstract

The reason for this research was the implementation of a wireless sensor monitor equipment powered by microbial fuel cells for the Alternative Energy and Environmental Research Center of Escuela Superior Politécnica de Chimborazo. The device is comprised of a sensor node charged to acquire data of ambient temperature and send them to a remote base station. The microbial fuel cells (MFCs) are devices charged of providing energy to the sensor node, although the amount of electrical power developed by the microbial activity is deficient the reason such, it was implemented an administration electronic system of energy (PMS) which stores and transform the received energy, to voltage rating and current required for the performance of the node. The implemented PMS which reached an efficiency of 59,58% when powered by sedimentary MFCs with a power of 0,2214 mV, allowing to the sensor node to send temperature data with an average frequency of 20,43 minutes. It was estimated through data sheets of the devices which comprises the PMS, the optimum performance that this could be achieved under the correct operating parameters, reaching 71,2%. It is concluded that the implemented equipment could be used for monitoring applications of weather variables as an ecological and environmentally friendly alternative. It is recommended to use MFCs that provide more power output to attain a better performance in the system.
