Abstract
The paper presents a method for optimizing the power consumption of the LoraWAN sensor node using the ESP32 microcontroller. We use an Espressif ESP32 microcontroller, a BMP280 pressure sensor, and a SX1276 LoRaWAN transmitter. By using the Ultra-Low-Power Coprocessor, included in the structure on the ESP32 microcontroller, to make measurements, instead of Xtensa® 32-bit LX6 microprocessor, we can reduce microcontroller power consumption. Optimization of the power consumption increases battery life and sensor node autonomous operations for years. We use the Wi-Fi interface of the microcontroller to access the web server of ESP32 to configure the parameters of the wireless sensor node.
