I just bought a few Grove sensors an want to use them on a distance from my Raspberry Pi. I got a GrovePi for connecting the sensors on the RaspberryPi, but the cables are only about 20 cm long. I need to place the sensors a lot further away from the Raspberry Pi. So this are my questions:
-
how long can the cable be for connecting the following sensors:
* Grove Dust Sensor ([url]http://www.seeedstudio.com/wiki/Grove_-_Dust_Sensor[/url])
-
Grove Barometic sensor (http://www.seeedstudio.com/wiki/Grove_-_Barometer_Sensor)
-
Grove Digital Light Senso (http://www.seeedstudio.com/wiki/Grove_-_Digital_Light_Sensor)
-
Grove Sound Sensor (http://www.seeedstudio.com/wiki/Grove_-_Sound_Sensor)
-
G1/2" Water Flow Sensor (http://www.seeedstudio.com/wiki/index.php?title=G1/2_Water_Flow_sensor)
If possible I would like to get the sensors about 10 or 15 m away from the board.
-
which cables should I use?
* standard telephone cable (4 wire, 0,7 mm², unshielded)
-
CAT 5e UTP cable (4 twisted pairs, unshielded)
-
shielded CAT 5e UTP cable (4 twisted pairs, shielded)
-
CAT 6e UTP cable (4 twisted pairs, unshielded)
-
shielded CAT 6e UTP cable (4 twisted pairs, shielded)
- Are there any Python sample codes available for reading the sensors? All examples I find are written for Arduino and not usable with a Raspberry Pi.
