Description: LDR Sensor Module

We are the leading suppliers for LDR Sensor Module. he LDR Sensor Module is used to detect the presence of light / measuring the intensity of light. The output of the module goes high in the presence of light and it becomes low in the absence of light. The sensitivity of the signal detection can be adjusted using potentiometer.

Features:

LM393 based designCan detect ambient brightness and light intensityAdjustable sensitivity (via blue digital potentiometer adjustment)Output Digital – 0V to 5V, Adjustable trigger level from presetOutput Analog – 0V to 5V based on light falling on the LDRLEDs indicating output and powerSpecifications:Operating voltage 3.3V-5VOutput Type Digital – Logic High or Low.Power indicator (red) and Output Indicator LEDs.Sensitivity can be adjusted using the on board potentiometer

Output Type:

Analog voltage output -A0Digital switching outputs (0 and 1) -D0With fixed bolt hole for easy installationSmall board PCB size: 3cm * 1.6cmPower indicator (red) and the digital switch output indicator (green)Using LM393 comparator chip, stable

How it works:

1.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;2.Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes;3.Digital output module DO can directly drive the relay module, which can be composed of a photoelectric switch;4.Analog output module AO and AD modules can be connected through the AD converter, you can get a more accurate light intensity value

Pin outs:

External 3.3V-5V VCCExternal GND GNDDO digital output interface, a small plate (0 and 1)AO small board analog output interface
