  • QTR-8RC is a reflectance sensor array but intended as a line sensor. It can be used as a general purpose proximity IR or reflectance sensor. The device has 8 pairs of IR LED and Phototransistor mounted on 9.525 mm pitch. 

    Each phototransistor in the module is followed by a pull-up resistor that forms a voltage divider and produces an analog voltage output between 0 to 5V as the function of the reflectance sensor. All the outputs are independent but LEDs are paired to halve the current consumption. The LEDs are controlled by MOSFET with a gate normally pulled high that allows LEDs to turn off by setting the MOSFET gate at low voltage. 

    Features

    • No analog to digital conversion requires
    • Improved sensitivity over voltage-divider analog output
    • Parallel reading of multiple sensors is possible
