LINE-01 - IR LINE SENSOR MODULE

IR Line Sensor Module

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 8bit 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 I?C interface for data communication. The I?C 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 I?C 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 linefollowing robot or used to detect the outer perimeters of a competition ring.
