CanAirIO, a citizen science project that aims to gather air quality data from around the world by putting sensors into the hands of as many people as possible

Its team has developed two different sensor nodes for this purpose: an indoor one that can measure CO2, and a mobile one that can measure particulate matter (PM) levels. Both versions are powered by an ESP32 microcontroller that reads out the air quality sensors and connects to the Internet using Wi-Fi or Bluetooth. The data can then be shared online to create detailed maps showing local variations in air quality.
The design of the sensor nodes is fully open-source, allowing anyone with basic electronic skills to build them.

Dashcam Detective Work Leads to Recovery of Space Rocks from Fireball over Slovenia

On 28 February 2020, at 10:30 CET, hundreds of people across Slovenia, Croatia, Italy, Austria and Hungary observed a bright ball of light hurtling across the morning sky. This delivery of rocks from a distant asteroid to the fields and villages of southern Slovenia was captured by cars’ dashcams, security cameras, and even a cyclist’s helmet. It is one of only around 40 fallen space rocks that has been recovered within weeks and for which the origins in the Solar System have been tracked.
