Light Sensor Analog Grayscale Sensor Electronic Board Includes a bright LED and a photosensitive resistor For Arduino

Grayscale sensor is an analog sensor,Used in conjunction with the sensor expansion board,Can feel the ground or desktop in different colors and the corresponding signal, can realize the interactive works associated with the color, but also can be used as field gray identification line sensor or the soccer robot patrol patrol line vehicle.

Operating voltage: 3.3V or 5V

Operating current: < 20mA

Operating temperature range: －10℃～＋70℃

Detection resolution: 10%

Interface type: analog signal output

Size: 30mm x23m

Working principle:

The gray sensor includes a white light emitting diode and a photosensitive resistance, because the light emitting diode irradiation to return different gray levels on paper is different, photoresistor receives the returned light according to different light intensity, photosensitive resistance is different, so as to realize the gray value test.

Programming principle:

Gray sensor leads to three pins, respectively is the power positive Vcc, power GND, signal S, the actual use can directly connect the sensor to analog interface of controller, such as analog A0, power, white bright LED light sensor, the sensor is buckled on a different gray level the paper, through the controller with the AD conversion data read, and then print out through the serial port analog can be measured.
