BEE Board 1-Wire Protocol

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)

Library to manage 1-Wire with BEE Board

The Arduino OneWire library is maintained by Paul Stoffregen

  • Download library here
  • Install library by following this guide.
  • open IDE and iclude OneWire library.

Create your OneWire application with Daisy-12

In this example the data pin is connected to pin 5 of the Daisy connector

Example: Read Temperature
