Environmental monitoring in remote or infrastructure-poor sites requires heterogeneous sensing, robust data logging, and long autonomy under strict radio and power constraints. This paper presents a modular, battery-powered multi-sensor node built around the RAK3172 LoRaWAN module (STM32WLE5) that combines low-rate telemetry with lossless local storage. The sensing suite targets indoor/outdoor air quality and microclimate monitoring: CO2, particulate matter, temperature and humidity are acquired using low-cost commercial modules. In a second hardware revision, the SPS30 particulate sensor was replaced by the SEN55 environmental node to consolidate PM plus VOC/NOx indices and T/RH into a single I2C module, improving field maintainability. A Bosch BME688 complements the suite with pressure and gas sensing, and a D7S seismic sensor adds event-oriented vibration indicators (SI/PGA) for structural-awareness use cases. Raw measurements are archived on a microSD card (SPI) while LoRaWAN uplinks provide compact aggregates and diagnostic flags for metrology-oriented traceability. Field operation in two heterogeneous sites shows reliable acquisition and supports downstream analytics; a simple standardized linear-regression baseline achieved R2 = 0.81 for PM2.5 forecasting on the collected dataset.

Abstract
Environmental monitoring in remote or infrastructure-poor sites requires heterogeneous sensing, robust data logging, and long autonomy under strict radio and power constraints. This paper presents a modular, battery-powered multi-sensor node built around the RAK3172 LoRaWAN module (STM32WLE5) that combines low-rate telemetry with lossless local storage. The sensing suite targets indoor/outdoor air quality and microclimate monitoring: CO2, particulate matter, temperature and humidity are acquired using low-cost commercial modules. In a second hardware revision, the SPS30 particulate sensor was replaced by the SEN55 environmental node to consolidate PM plus VOC/NOx indices and T/RH into a single I2C module, improving field maintainability. A Bosch BME688 complements the suite with pressure and gas sensing, and a D7S seismic sensor adds event-oriented vibration indicators (SI/PGA) for structural-awareness use cases. Raw measurements are archived on a microSD card (SPI) while LoRaWAN uplinks provide compact aggregates and diagnostic flags for metrology-oriented traceability. Field operation in two heterogeneous sites shows reliable acquisition and supports downstream analytics; a simple standardized linear-regression baseline achieved R2 = 0.81 for PM2.5 forecasting on the collected dataset.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
