WiFi Data Acquisition System and online monitoring applied to thermoelectric microgeneration modules
The Renewable Energies and Power Quality Journal (RE&PQJ)
The present paper describes the development of an online monitoring and WiFi data acquisition system using free software applied to microgeneration based on thermoelectric modules. Monitoring and data acquisition systems are applicable in various stages of the microgeneration process, e.g., in the energy resource evaluation, generation failures prognosis, practical verification of project data and efficiency of generation. The online monitoring and data acquisition system was developed using a
... developed using a WiFi modem coupled to a microcontrolled board based on free software. This monitoring system was applied to thermoelectric modules and was also developed a wireless communication with the online server which sends microgeneration values to the data bank. The free software for online monitoring and WiFi data acquisition allows the analysis of stored data and charts through mobile devices as notebooks, tablets and smartphones. Moreover, the system can also be expanded to record values from analogical or digital sensors used in plants based on other renewable energy sources.
