Infrared Reflectance Sensor
The Infrared Reflectance Sensor Module carries a single infrared LED and photo transistor pair in an inexpensive, tiny module that can be mounted almost anywhere and is great for obstacle detection of robot and home alert system.
Building interactive work is as easy as piling bricks, just plug it in the Sensor Shield with a buckled cable, and make it looks professional and neat.
The Infrared Reflectance Sensor Module simply gives a digital signal when it detects infrared reflection from a person or object, so the code is exactly as the one we would use for a push button.
Please be noted that, when reflection is detected, it gives a“low” value.
Red: VCC; Black: GND; Yellow: Signal Data
Working voltage: 5 VDC
Working current: 10-15 mA
Drive current: 100 mA
Induction distance: 1Meter
Size: 18 x 45 mm
Lead length: 18 cm
Connection: red take 5 V, black meet GND, yellow line output. Through the sensors to adjust the knob on the back, the distance sensitivity can be varied .In range, no obstacle yellow line output 5 V, with an obstacle yellow line 0 V.(the power supply voltage stability)
In the circuit design can be in the output and the yellow line, resistance to 10 K 5 V, again, chip will test access is stable and the single-chip microcomputer testing can use external hardware interrupt INT0 INT1 to achieve.
