Photodiode Sensor Module for Light Detection เซ็นเซอร์ตรวจจับแสง

• Can detect the brightness of surrounding environment and the light intensity (with a photoresistor comparison, good directivity, can perceive the fixed direction of the light source)
• Adjustable sensitivity adjust the digital potentiometer (shown in blue)
• Operating voltage 3.3V-5V
• Digital switch outputs (0 and 1), Analog output 
• Has a fixed bolt hole for easy installation
• Small plates PCB size: 3.2cm * 1.4cm

• VCC - 5V
• GND - GND
• DO - Output

Serial.begin(9600);

 

}

 

void loop() {

Serial.println(digitalRead(2));

delay(200);
