Overview
Air quality data in Africa is scarce. Government monitoring networks are sparse, reference instruments are expensive, and what data exists is rarely accessible to the public in a usable form.
Hewa Analytics was built to change that. The platform aggregates live readings from OpenAQ, Open-Meteo, and Sensor.Community and presents them through a clean, interactive map. Sensors are grouped by city, PM2.5 readings update in real time, and everything is free to access without an account.
What we built
A public map anyone can use: City-level sensor locations across Africa with live PM2.5 readings and color-coded air quality index overlays.
Data pipelines built for reliability: Automated ingestion from multiple sources with time-series storage for historical analysis.
Tools for serious users: Logged-in users get personal dashboards, configurable email alerts, and downloadable reports.
Who uses it
Governments and environmental agencies: Monitoring data to inform policy.
Researchers and public health NGOs: Historical time-series data for studies.
The general public: Checking local conditions before outdoor activities.
Live platform
Hewa is live at hewanalytics.muransystems.com.
“Hewa Analytics fills a real gap. For the first time, a researcher in Kisumu or a government officer in Mombasa can see live air quality data for their city, on their phone, for free.”
