#DS18B20 Library for Particle Core, Photon and P1 Modified DS18BXX Lib copied from https://github.com/krvarma/Dallas_DS18B20_SparkCore Sample application using Particle Photon and Dallas DS18B20 Digital Temperature Sensor. The OneWire source code is taken from this link by @tidwelltimj. I just separated this into two classes OneWire and DS18B20. The sample code publishes a variable named tmpinfo with temperature value.

Requires Particle-OneWire (included) from https://github.com/balbano/OneWire-Particle/tree/master/firmware Wiring: Power to 3.3/5V GND to GND Signal to D2 (with 4.7k pullup resistor)

Use crcCheck() to verify the sensor was successfully read.
