For some time, we have been working with atmospheric researchers to add instrumentation to quadcopters and radio-controlled airplanes. These are also called Unmanned Aerial Vehicles (UAV) or Remotely Piloted Air System (RPAS).
This is organized in the ISARRA community.
Now we announce a system specifically for this purpose, Sparv Sensors. It removes the need for researchers to also be engineers when setting up UAVs to measure temperature, humidity, gases, etc.
