A buffer to prevent the sensor from bouncing between standard operation and aware state when the assessments are very close to a threshold. for example, if a maximum threshold is set to 90 degrees and a hysteresis of 1 degree, then once the sensor takes an assessment of 90.0 degrees and enters the aware state it will remain in the aware state until the temperature readings drop to 89.0 degrees @param hysteresis value determined by sensor type
