[clug] Raspberry Pi WLAN issues

[Stephen Gibson]

I had the wrong device number for the humidity sensor command, should be type 11, not 2302:

sudo ./Adafruit_DHT 11 4
Using pin #4
Data (40): 0x33 0x0 0x12 0x0 0x45
Temp = 18 *C, Hum = 51 %

cf the DS20B18 temperature sensor:

[Rpi512:~]$ !cat
cat /sys/devices/w1_bus_master1/28-00000559ff29/w1_slave 
2e 01 4b 46 7f ff 02 10 38 : crc=38 YES
2e 01 4b 46 7f ff 02 10 38 t=18875

So, both sensors appear to give the same temperature reading. The DS20B18 is stated to be accurate to +-0.5C.
