- 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)
- 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
- VCC = 3.3V to 5V DC
- GND = Ground
- DO = Digital Output
- AO = Analog Output
- 1 x?LDR MODULE
