With Raspberry Pi
1. You should have got a raspberry pi and a grovepi or grovepi+.
2. You should have completed configuring the development enviroment, otherwise follow here.
3. Connection.
 Plug the sensor to grovepi socket D6 by using a grove cable.
4. Navigate to the demos' directory:
cd yourpath/GrovePi/Software/Python/
 To see the code
nano grove_mosfet.py # "Ctrl+x" to exit #
import time
import grovepi
