QTR-3RC Reflectance Sensor Array, Pololu Robotics and Electronics

QTR-3RC Reflectance Sensor Array This compact module packs three IR LED/phototransistor pairs onto a 1.25 ? 0.3 board. The sensors are mounted on a 0.375 pitch, allowing this array to be used as a minimal detector for a line-following robot. Each sensor provides a separate digital I/O-measurable voltage output. The QTR-3RC reflectance sensor array is intended as a line sensor, but it can be used as a general-purpose proximity or reflectance sensor. The module is a convenient carrier for three IR emitter and receiver (phototransistor) pairs. With sensors spaced at intervals of 0.375 (9.525 mm) along of the board's longer axis, this array works well as a minimal detector for line-following robots, as line-following courses are commonly made using 3/4 (19 mm) black electrical tape. The middle sensor is slightly offset along the short axis of the board. Each phototransistor uses a capacitor discharge circuit that allows a digital I/O line on a microcontroller to take an analog reading of reflected IR by measuring the discharge time of the capacitor. Shorter capacitor discharge time is an indication of greater reflection. The LED current-limiting resistors are set to deliver approximately 17 mA to the LEDs when VCC is 5 V, making the total board consumption just over 50 mA. Specifications Dimensions: (32 mm?8mm?3 mm) (without header pins installed) Operating voltage: 5.0 V Supply current: 50 mA Output format: 3 digital pulse signals Optimal sensing distance: (3 mm) Maximum recommended sensing distance: (6 mm) Weight without header pins:(0.6 g)
