Lm393 Optical Photosensitive LDR Light Sensor Module for Arduino Shield DC 3-5V

  • Rs. 80.00 INR

TECH1467

Specification:

  • Operating Voltage: 3.3V to 5V DC
  • Operating Current: 15ma
  • Output Digital – 0V to 5V, Adjustable trigger level from preset
  • Output Analog – 0V to 5V based on light falling on the LDR
  • LEDs indicating output and power
  • PCB Size: 3.2cm x 1.4cm
  • LM393 based design
  • Can detect ambient brightness and light intensity
  • Adjustable sensitivity (via blue digital potentiometer adjustment)

 

Description:

  • The Light Sensor generates an output signal indicating the intensity of light by measuring the radiant energy that exists in a very narrow range of frequencies basically called “light”, and which ranges in frequency from “Infra-red” to “Visible” up to “Ultraviolet” light spectrum
  • 100 percent brand new and high quality using a wide voltage lm393 comparator with a mounting screw hole,
  • LDR Module Photosensitive resistor module most sensitive to environmental light intensity is generally used to detect the ambient brightness and light intensity.

 

How it works:

  • Module light conditions or light intensity reach the set threshold, DO port output high when the external ambient light intensity exceeds a set threshold, the module D0 output low;
  • Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes;
  • Digital output module DO  can directly drive the relay module, which can be composed of a photoelectric switch;
  • Analog output module AO and AD modules can be connected through the AD converter, you can get a more accurate light intensity value

 

Pins:

  • VCC = 3.3V to 5V DC
  • GND = Ground
  • DO = Digital Output
  • AO = Analog Output

 

Packaging Included:

  • 1 x LDR MODULE
