Análisis comparativo del consumo de energía de sistemas embebidos avanzados entre WiFi y Ble para el envío de datos hacia plataformas en la nube

Abstract

This academic article is based on the analysis and comparison of the energy consumption of advanced embedded systems using Wi-Fi and Bluetooth modules that are connected to IoT platforms. The objective of the analysis is to define the module that consumes the least energy. Different experimental scenarios (WIFI and BLE) were implemented, where the measurement was carried out using the invasive method of the shunt resistance, applied to the current input of each module. From the results obtained, it was observed that the device with the highest energy consumption in data transmission is the ESP32 with 89% compared to the BLE module, which is better in terms of energy saving. The bluetooth HC-05 is the second device with the highest consumption followed by the ESP8266, therefore, it is the HC-06 that consumes twice as much energy as the BLE (3 mW), in a condition of data transmission to the cloud, neglecting the consumption of the module. Resulting in that the device with the lowest energy consumption is the BLE thanks to its protocols that only collect and send information but do not process it.
