Monitoring air quality in a titanium mine

Mining is an activity that generates high rates of pollution, which affects the environment of the site and it surrounding areas, as well as the health of the workers and local residents. Mining is therefore regulated and requires the quality of the air to be monitored.
Rio Tinto, a multinational mining group, wanted to install simple, reliable and efficient monitoring systems to meet its legal obligation to ensure the health and safety of the employees and of neighboring people, at their site in Madagascar. The company was looking for a solution: 
  • Energy independence
  • Easily transported
  • Multi parameters
  • Connected to the internet
  • Robust


  • Installing several professional stations (EcomSmart) connected using the 3G network for hyperlocal air quality data: NO2, SO2, O3, PM1, PM2.5, PM10
  • Positioning solar panels on the stations to provide energy in the absence of electricity
  • Storing data on a secure web server 
  • Making available the EcomSaaS web platform services to monitor the environmental data via a secure protocol (SSL): data visualization, mapping, storage, downloading, remote control, alarms/alerts, data analysis reports, exchange of data (FTP transfer, API link, export database)


  • Ability to monitor up to 6 pollutants (PM1, PM2.5, PM10, CO2, CO, NO2, SO2, H2S, O...), 3 environmental parameters (temperature, humidity, pressure) and integrated GPS
  • Ongoing quality of measurements (near reference)
  • Easy access to data and data analysis : 
    • Data can be accessed from any terminal in SaaS mode (visualization and downloading are possible)
    • Data downloading (directly or by .xls or .csv) to produce reports
  • Easy deployment allowing the densification of the monitoring network in addition to the reference stations
    • Compact and light-weight
    • Easy-of-use, ease of installation and maintenance
    • Affordable
