Transformación digital: modernización del sistema de registro hidrometeorológico del PROMAS

Abstract

In this work, a hydrometeorological data logging device is designed and implemented, integrating LoRa technology into an ESP32-S3 microcontroller. The device consists of two PCB modules: the first includes connection ports for station and general-purpose sensors, an ADC module, a counter, an RTC module, and a power switch; the second module integrates the ESP32 microcontroller and the LoRa chip. The software is designed to minimize power consumption by reducing the CPU operating frequency, using Deep Sleep mode, and implementing the VMTP frame model. Measurements of temperature, humidity, wind speed and direction, precipitation, solar radiation, and UV radiation, as well as information on sensor operation and the time of measurements, are sent to the TTS server using the LoRaWAN network protocol, to later establish communication with Thingsboard and present the information in a dashboard. The device demonstrated good performance in field tests, enabling the collection and validation of environmental monitoring data.
