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 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. Features Plug and play with OSEPP I²C Expansion Shield Two IR sensors per board with independent outputs Flexible blackness threshold that can be set via software setting 8-bit ADC for digitizing sensor output, sample rate up to I²C frequency Support I²C interfacing with 4 programmable 7-bit address: 0x48, 0x49, 0x4A, 0x4B Provides pass-through connector to support daisy chaining of multiple sensors from the OSEPP Sensor Module family Provides 0.1” breakout points for power and I²C interface pins access
