## Description

OVERVIEW The OSEPP IR Line Sensor Module differentiates the reflections between dark and light surfaces. It utilizes the Fairchild QRE1113GR miniature reflective object sensor and the NXP PCA9691 A/D converter. The 8-bit A/D converter digitalizes the sensor output. The sensor operates by emitting an IR signal via an LED, and then measuring the amount of reflection to determine the blackness of the surface. The module uses the I²C interface for data communication. The I²C lines are packaged with the power and ground lines into a modular connector, which allows easy plug and play operation. There are two connectors on the module to enable daisy chaining of multiple I²C devices together. This sensor module is ideal for designs that required to track black line on a white surface (or vice versa), such as in a line-following robot, or used to detect the outer perimeters of a competition ring. HIGHLIGHTS • I²C Addresses (7-bit): 0Ã-48, 0Ã-49, 0x4A, 0x4B • Form Factor: 23 mm x 36 mm • Power Consumption: 400 mW • Connector Pin Definition: Pin 1: Power, Pin 2: I²C Data, Pin 3: Ground, Pin 4: I²C Clock
