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 LEDs and phototransistors ed on a 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. A parallel reading of multiple sensors is possible. Specification: Operating voltage: 3.3 to 5V Current supply: 100mA Output voltage range: 0V to supplied voltage Output format: 8 digital I/O compatible signal Sensing distance: 3mm Maximum sensing distance: 9.5mm Application: Line following robot DIY electronics and robotics projects Package Includes: 1 x QTR-8RC Line Following Reflectance IR Sensor Array. 1 x Burg strip.
