Node Handheld Sensor Looks Like Star Trek Medical Tricorder
Variable Technologies just put out several external Bluetooth smartphone sensors called Nodes. The Node is about the size and shape of a roll of quarters, uses Bluetooth 4.0 and features an accelerometer, magnetometer, gyroscope, barometer, thermometer, altimeter light-meter, humidity meter, heat-mapping, and programmable LEDs. The device is currently working for iOS 4 and on several Android devices.
The device looks awfully familiar to a device featured on Star Trek The Next Generation – a Medical Tricorder.
Engadget did a hands-on with the device and grabbed some sensor shots:
