For air quality monitoring in Africa and around the world, where sparse regulatory networks and challenging infrastructure often affect data collection, remote air quality sensors are an affordable ultimatum.
Clarity Movement provides advanced, IoT-enabled air quality monitoring solutions that combine precision sensing with global connectivity. The Clarity Node-S, integrates solar power,...
Abstract: This work is a review of the various applications of low-cost electronic sensors used for environmental monitoring. It aims to provide an overview of the design, development, and application of electronic devices that we have carried out over the past five years in our research institute in Cameroon. These devices measure : air quality (Carbon monoxide (CO), Carbon Dioxide (CO2),...
AI_R is a low-cost, scalable air-quality monitoring and prediction system that uses efficient sensing hardware, affordable IoT connectivity, and AI-based analytics to support informed decisions in public health, risk management, and environmental governance. The system includes two sensing solutions: an outdoor unit built around the Sensirion 55 sensor and the Nordic nRF9160 LTE-M/NB-IoT...
Rapid urbanization and the growing demand for sustainable mobility are intensifying challenges related to air pollution and environmental management across African and global cities. This contribution introduces a smart pollution monitoring framework that integrates real-time environmental sensing with compact, low-power instrumentation to support cleaner and more efficient transportation...
This study, conducted as part of the European DACCIWA project (Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa), presents the first long-term measurements of atmospheric ammonia (NH₃) near the Akouédo landfill in Abidjan, Côte d’Ivoire. From February 2015 to March 2017, simultaneous passive sampling was performed using INDAAF sensors and ALPHA badges. Ammonia concentrations were...
The present work aims to investigate the presence and related concentration of different pollutants and their species in a wide range of ambient air particulates collected from different regions in the Middle East. Ambient air particulates were collected from different cities in the Middle East including; Cairo-Egypt, Amman-Jordan, Taif, and Jeddah-Saudi Arabia. The collected particulates are...
This study evaluates the performance of the low-cost AirQino sensor for measuring PM₁₀ concentrations in a humid savanna environment at the Lamto Geophysical Station, Côte d’Ivoire. A 40-day co-location campaign was conducted with a reference TEOM analyzer. Raw results indicate a moderate but significant correlation between AirQino and TEOM measurements (r = 0.51; R² = 0.26), with a systematic...
In this study, we performed comprehensive first-principles calculations based on density functional theory to investigate the structural, electronic, mechanical, thermodynamic, and optical properties of α-nickel sulfide (α-NiS), with a particular emphasis on its potential for CO2 adsorption. Structural optimization confirms the stability of the α-NiS phase, yielding lattice parameters, a = b =...
It is well-known the limitations that low-cost sensors have related to the environmental conditions effect, cross-sensitivities, and drifts over time. Currently, manufacturers apply different techniques to mitigate these limitations, most of them based on Machine Learning and AI models. However, these models have several disadvantages, such as they require a large amount of reference data to...
Source apportionment methods are key to understand the complex, non-linear contribution processes of different emitting sectors to ambient air quality and the potential benefits on air quality that emission abatement measures may entail. This contribution illustrates the application of the Decoupled Direct Method (DDM) as the basis of a platform to inform and support the decision-making...
