	The ~~infrared sensor~~ can detect an object at 5mm. It measures the amount of energy from the object and returns a value between 0 and 1000. A returned value between 0 and 400 signifies that the object has been detected. Values over 400 indicate that there is no reflective object within range, or that an object is too close.		The 1102 can detect an object at 5mm. The 1102 consists of an infrared emitting diode and an NPN silicon phototransistor mounted side by side on a converging optical axis in a black plastic housing. The phototransistor responds to radiation from the emitting diode only when a reflective object passes within its field of view. The area of the optimum response approximates a circle 5mm in diameter.

	The amount of reflectivity is measured by infrared and some materials that look very reflective to the human eye might not be as reflective in the infrared spectrum. The sensor can only detect objects that are between 3 to 7 mm away; it cannot see any objects outside that range.

	When working with sensors that are not digital, it is helpful to filter out noise by implementing a simple hysteresis in your code. By interpreting any ~~SensorValue < 400~~ as a detection, and not releasing the detection until ~~SensorValue goes~~ above some higher threshold, such as ~~500~~, multiple triggering can often be avoided.

By interpreting any voltage less than 2V as a detection, and not releasing the detection until the voltage rises above some higher threshold, such as 2.5V, multiple triggering can often be avoided.

	Finally, the 1102 works best in a constrained environment, where objects can be mechanically guaranteed to be within the 3-7mm range, or not present at all.
