The IR Locator has four IR detectors facing forward, back, left, and right. The IR intensity recieved by each of these sensors allows the on-board processor (or PIC) to calculate the direction of the IR Light source to within 5 degrees. The IR Locator can be set to read 1200 or 600Hz IR Light.
Sensor Type: Four Wire I2C Sensor
Default 8-bit I2C Address: 0x1C
Arduino 7-bit I2C Address: 0x0E

The heading value is returned in 5 degree incriments from 0 to 71. If an object were to circle the sensor in a clockwise direction, the value of degrees will increase. If the object were to circle in a counter clockwise direction, the value of the heading will decrease.
