Product Description



product description
The grayscale sensor is an analog sensor. It can be used in combination with the Arduino sensor expansion board v5.0 to sense different colors on the ground or the desktop to generate corresponding signals. It can realize interactive works related to color, and can also be used as a tour of the patrol car. Grayscale recognition of the field sensor or soccer robot. The power supply needs to be the same as the controller, usually 3.3V or 5V.

Working voltage: 3.3V or 5V
Working current : < 20mA
Operating temperature range: -10 ° C ~ +70 ° C
Detection resolution: 10%
Interface type: analog signal output
Size: 24mm x 21mm
Weight: 3g

Interface definition
OUT: signal output
VCC: Power Supply (VCC)
GND: Ground (GND)

working principle
The gradation sensor comprises a white high-brightness light-emitting diode and a photoresistor. Since the light returned by the light-emitting diode on different gradation papers is different, the photoresistor receives the returned light, and the photoresistor is different according to the intensity of the light. The resistance values ​​are also different, so that the gray value is tested.

Programming principle
The gray level sensor has three pins, which are power supply positive Vcc, power supply ground GND, and signal terminal OUT. In actual use, the sensor can be directly connected to the analog interface of the controller, for example, analog port A0. After power-on, the sensor is white high. The bright LED lights up, and the sensor is placed on the paper with different gray scales. The data is read by the AD conversion of the Arduino controller, and then the measured analog quantity is printed through the serial port.

The OUT port is connected to the analog input pin of the controller. Connect 5V and GND to the +5V and GND of the power supply, respectively.
