Circular Arduino MKR IoT Carrier board is full of sensing Now joining the Arduino MKR series of boards – aimed at IoT projects – is the MKR IoT Carrier, a new carrier board with a colour display and embedded sensors. Small and circular, it can read fingerprints, there’s a proximity sensor for swiping your hand across the face of the device, a motion detector, colour detection, gesture sensing and environment sensors also relay temperature, humidity and air pressure. It’s all displayed in a cute central circular screen. And there are also five RGB Leds up for grabs. Check out the video below to see how easy the MKR IoT Carrier is to use. Just plug in the SD Card and battery and go.
