 Detailed Description
Reflective Obstacle Sensor
The sensor has a I/R LED and a I/R detecting photo transistor. Transistor is connected to a LM393 voltage comparator IC with adjustable trigger level. The detection distance is a function of target reflectivity and shape. The LED indicator turns on when an object is detected (Output switches LOW). The output can be connected directly to a microcontroller port or add a driver transistor to the output, & it could switch a relay or other loads exceeding 20mA.
Power: 3.3V to 5V
Supply Current < 1mA (LEDs off)
LEDs: 2: Red for Power and Green for Detection
Output: Digital TTL Current sink 20mA, 10K Pull-up
Connections: 3Pin, .1in. Pitch Header.
L: 47mm OA W: 14mm H: 8mm WT: .02

Buy more than you need.
Works perfectly. Or...doesnt work at all, right out of the package. Other than the failure rate, these are great for lots of uses. In pairs, they make nice interrupters up to two feet apart.

Work very well with an Arduino
I have used these for a signaling system for a model railroad with an Arduino processor. They work very well and are easy to interface. These are good for detecting items. They can easily be adjusted for sensitivity.
