This is really cool. With the phone connection, it kinda reminds me of the extra probe on Medical Tricorders (from Star Trek), where that device had additional sensors, and was smaller and easier to move around a patient's body. Likewise, this instrument can be placed in locations where a smartphone would be difficult to position and read. Or it can be a small distance away - put the sensor outside while you remain comfortably indoors. Put the sensor inside a centrifuge while you remain relatively stationary. Put the sensor inside a model rocket while you remain on the ground. I can't wait to see these put on RC cars and drones and RC blimps.
