Abstract

In the scenario of massive urbanization and global climate change, the acquisition of microclimatic data in urban areas plays a key role in responsive adaptation and mitigation strategies. The enrichment of kinematic sensor data with precise, high-frequency and robust positioning directly relates to the possibility of creating added-value services devoted to improving the life-quality of urban communities. This work presents a low-cost cloud-connected mobile monitoring platform for multiple environmental parameters and their spatial variation in the urban context.

Highlights

  • The recent evolution of IoT devices opens up to new possibilities for urban monitoring, especially in the validation of current theoretical models and numerical simulations, as well as, to provide support and evidence in the process of decision- and policy-making [1]

  • The hardware is based on a U-blox ® C099-F9P application board [9] set as the low-cost Global Navigation Satellite System (GNSS) receiver, coupled with a Raspberry Pi (RPi) [10]

  • The LEICA ® high-accuracy GNSS set has been placed in the inner courtyard of the NOI Technology Park, far from typical GNSS source of disturbances

Summary

Introduction

The recent evolution of IoT devices opens up to new possibilities for urban monitoring, especially in the validation of current theoretical models and numerical simulations, as well as, to provide support and evidence in the process of decision- and policy-making [1] In this framework, mobile microclimatic monitoring plays a crucial role, when kinematic sensors’ data are enriched with precise, high-frequency and robust positioning capabilities. Despite the possibility of an improved spatio-temporal resolution, standalone low-cost mobile prototypes with (i) accurate localization capacity (differential GNSS positioning capabilities) and (ii) transmitting measurements in real-time are still not common in urban and peri-urban environment It is still challenging, both for costs and accuracy aspects, to accomplish autonomous outdoor devices with reliable positioning, as recent studies have pointed out [5,6]. There are advantages of using such GNSS receivers like lower power intensity, portable size, and high integration, to name a few [8]
