8 Channel Reflectance Sensor Array Module Qtr-8a 840 Point Breadboard 5mm PCB Screw Terminal BlockThe QTR 8A reflectance sensor array is intended as a line sensor, but it can be used as a general purpose proximity or reflectance sensor. The array module is a convenient carrier for eight IR emitter and receiver (phototransistor) pairs evenly spaced at intervals of 0. 375 (9. 525mm). Each phototransistor is connected to a pull up resistor to form a voltage divider that produces an analogue voltage output between 0V and VIN (which is typically 5V) as
