EASY plug Photocell Sensor


A photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The principal is very simple. The resistance of photoresistor varies with incident light intensity. If the incident light intensity is high, the resistance decreases; if the light intensity is low, the resistance increases.
keyestudio EASY Plug photocell sensor is a semiconductor, integrated with a photoresistor, easy to use and very convenient for wiring.
It has features of high sensitivity, quick response, spectral characteristic and R-value consistence.
It can be applied in light-sensitive detector circuits, intelligent switch design and light- and dark-activated switching circuits.
Note: this module should be used together with EASY plug control board.


  • Interface: Easy plug
  • Sensor type: analog
  • Working voltage: 5V
  • Quick response

Technical Details

  • Dimensions: 38mm*20mm*18mm
  • Weight: 4.3g

Connect It Up

Connect the EASY Plug photocell sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Copy and paste below code to Arduino IDE and upload.

int sensorPin =A2 ;
int value = 0;
void setup()
Serial.begin(9600); }
void loop()
value = analogRead(sensorPin);
Serial.println(value, DEC);

What You Should See

Done uploading the code, you should see the analog value change in accordance with how much light your photoresistor is sensing.
