+'''
+  This is based on the widely available DS18B20 temperature probe.
+  It is a 1-wire protocol device that returns temperature directly
+  degrees C.  The dataline must go on the Pi GPIO 4 (pin 7) which
+  should be pulled up to VCC with a 4.7K resistor.
+
+  You have to do several thingsto make this work:
+
+    1) Enable 1-wire support in the Pi:
+
+        edit /boot/config.txt set: dtoverlay=w1-gpio
+        reboot
+
+    2) Each 1-wire device is connected to the same pin (7)
+       on the Pi.  It distinguishes between them by a uniq
+       address.  You have to find that address *for your specific
+       device*.  You do this by looking at:
+
+         ls -l /sys/bus/w1/devices
+
+       You'll see the ID of your device there.  That needs to
+       be set in the line below for this code to work with
+       your device.
