Things that can interfere with a sensor include, but are not limited to, the material's translucency, reflectiveness, color, temperature, chemical composition, and even the angle at which the object is reflecting the radiation back at the sensor. As such, proximity sensors should not be relied on as a means to measure distance: the only thing that can be deduced from a proximity sensor is that an object is somewhere in the distance between the minimum device proximity and the maximum device proximity with some degree of certainty."

just two tiny nits above, please change:

"minimum device proximity and the maximum device proximity" 
"minimum sensing distance and the maximum sensing distance".
