In this example it is set to pin 2 but can be changed to ay pin that can tolerate being pulled up at power on. | + | DS18B20_Pin defines the pin to use for the 1-Wire bus (DQ line).

| - | sleepTimeS specifies the delay in seconds between readings. We don't actually sleep but rather simply delay a specified amount of time in seconds before that next temperature update. It's important to keep this relatively course as we don't wont to flood Particle.io with constant updates to the log. For slow changing inputs, 30 seconds to 1 minute is about right but you can easily change this to suit your own needs. | + | sleepTimeS specifies the delay in seconds between readings.
