Gray Scale Sensor Module - 3.3V/5V Analog Signal Output with OUT VCC GND for Robot Line Tracking - Perfect for Robotics Projects, Arduino DIY, and STEM Education Applications

Feature:1. ANALOG SENSOR: The grayscale sensor is an analog sensor, used in conjunction with the sensor expansion board v5.0, can perceive different colors and generate corresponding signals.2. GRAY VALUE TEST: Including a white high brightness LED and a photoresistor, according to the strength of the light, to achieve the gray value test.3. 3 PIN DESIGN: With 3 pins, which are power positive VCC, power ground GND, signal terminal OUT, which can be directly connected to the analog interface of the controller.4. MULTIPLE USAGES: Can realize interactive works related to color, and can also be used as a line following sensor or a football robot field gray recognition.5. EXAMPLE PROGRAM: Connect the grayscale sensor to the controller according to the program, and observe the value output by the serial port under different grayscale values.How to Use:Connection Instructions: The OUT port is connected to the analog input pin of the controller. 5V and GND are respectively connected to +5V and GND of the power supply.Example Program: Connect the grayscale sensor to the controller according to the program, and observe the serial port output value under different grayscale valuesSpecification:Item Type: Grayscale SensorWorking Voltage: 3.3V or 5VWorking Current: <20mAOperating Temperature Range: -10℃-70℃Detection Resolution: 10%Interface Type: Analog signal outputBoard Size: Approx. 24 x 21mm / 0.9 x 0.8inInterface Definition: OUT: Signal OutputVCC: Power (VCC)GND: Ground (GND)Package List:1 x Grayscale SensorNote:The power supply needs to be consistent with the con
