This article illustrates how to manage a Dallas DS18B20 thermal sensor to the BeeBoard and how to read the temperatures using the OneWire library
"The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements. It communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55C to +125C and is accurate to +-0.5C over the range of -10C to +85C. In addition, the DS18B20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply" (read more)
The Arduino OneWire library is maintained by Paul Stoffregen
In this example the data pin is connected to pin 5 of the Daisy connector
DAISY-12 is a 40x40 mm prototyping board with daisy IDC connector mounted and small soldering area to create your custom daisy add-on module.
Note: the daisy flat cable to wire this board is not included. Don't forget to buy it (code FLAT-20CM)
1-wire Dallas DS18B20 thermal sensor
The Dallas/Maxim DS18B20 is a 1-wire digital thermometer:
1 meter of 10 wires flat cable for Daisy wiring
1 meter of grey conductor flat cable, .025" pitch, 10 wires at 30 AWG, to use for Daisy wiring.
