At a glance
An open environmental sensing system for temperature, humidity, PM2.5, light and TVOC, expandable with CO2, noise and wind-speed modules.
Measures temperature, humidity, PM2.5, light and TVOC, and can be expanded with CO2, noise and wind-speed modules for different applications.
MAPS 6.0 is an open system in the spirit of the LASS community — “visible, modifiable, and the data belongs to everyone”. The hardware, software and recorded data are publicly available, so anyone can build their own version under the MIT licence (system tools and supporting services excluded).
