Light Sensor Module LDR Photo Resistor Module for Raspberry Pi Arduino Uno AB070

Package include

1 / 2 / 3 pcs module – as you have chosen

DESCRIPTION

The Photoresistor Light Sensor Module can detect the presence or absence and the relative strength of visible light.

  • Detects visible light spectrum
  • Analog output
  • 3.3 and 5V compatible

This module incorporates an photoresistor, also called an LDR (Light Dependent Resistor).  A photoresistor is a resistor whose resistance changes with the amount of light striking it.

The photoresistor is in series with a 10K resistor to create a voltage divider.  The output of the module is analog and is at a low voltage when no light is striking the sensor and the voltage rises as the light intensity increases.  Under strong lighting, the output will approach Vcc.  When the light is completely blocked, the output will approach ground.

TECHNICAL SPECIFICATIONS

Operating Ratings Vcc Range 3.3 – 5V
Strong Light > 4.2V (with 5V Vcc)
No Light < 0.25V
 Dimensions L x W (PCB) 20 x 16mm  (0.75 x 0.6″)
