a bicycle-mounted roving detective kit for urban investigation

designer:  Ryan Lewandowski

Fastened to a bike via a shock mount,  Sherloc is a battery operated urban sensor device that records the temperature, humidity, light, and airborne particulate matter that is then geolocated with the onboard GPS device. This information is stored as a Comma Separated Value (CSV) file that can be easily mapped within Grasshopper to create parametrically driven data landscapes or surfaces for a city or site.

The device  will take readings once every 2-4 seconds. Once your trip has been completed, just press the power switch to end the recording. To retrieve the recording, unscrew the top of the box and remove the MicroSD card from the shield on the Arduino. Plug it into your computer and you have a formatted CSV file that can be opened in Excel or read directly through Grasshopper!

Sherloc also has o-ring mounts for an iPhone.  This is specifically for apps that record decibel levels and topography, but app-space contains many as-yet-unexplored regions…
