Grove - Temperature Sensor
The Grove -Temperature Sensor detects the ambient temperature by including a thermistor, whose resistance will increase when the ambient temperature decreases and vice versa.
This component page contains the wiring information, hello world code, and demo video of Grove - Temperature Sensor with ARMmbed.
There are demo code online with Arduino, Raspberry Pi ,and Beaglebone Green. http://www.seeedstudio.com/wiki/Grove_-_Temperature_Sensor
