Qre113 digital ir infrared reflective sensor module linear sensor breakout board 3.3v 5v output for line following robot
Description:
This version of the qre113 breakout board features a digital output, using a capacitor rechargeable circuit to measure the amount of reflection. This tiny board is perfect for line sensing when only digital i / o is available, and can be used in both 3.3v and 5v systems.
The board 's qre113 ir reflectance sensor is compressed of two parts an ir emitting led and an ir sensitive phototransistor. When you apply power to the vcc and gnd pins the ir led inside the sensor will illuminate. A 100 resistor is on-board and placed in series with the led to limit current. The output of the phototransistor is tied to a 10nf capacitor. The faster that capacitor discharges, the more reflective the surface is.
These sensors are simply used in line following robots. White surfaces reflect more light than black, so when directed towards a white surface, the capacitor will discharge faster than it would when pointed towards a black surface.
The power input and output pins are brought out to a 3-pin, 0.1 pitch header. The board also has a single mounting hole if you want to screw it ono something.
Operating voltage: 5v dc
Current: 25ma
Digital i / o compatible
No. Adc required.
Optimal sensing distance: 0.125 "(3mm)
0.3x0.55 "
Package included:
1 x ir reflective sensor module
1 x pin h
