4Pin LDR Module – Optical Sensitive Resistance Light Detection Sensor Module

Description

4Pin LDR Module – Optical Sensitive Resistance Light Detection Sensor Module Using the sensitive type photoresistor sensor The comparator outputs a signal clean, good waveform driving ability more than 15mA. With adjustable potentiometer can adjust the light intensity detected The working voltage: 3.3V-5V The output format: Digital switching output (0 and 1) With a fixed bolt holes for easy installation Small PCB board size: 3.2cm x 1.4cm Using a wide working voltage range LM393 comparator Application: Light intensity is detected, the light intensity sensor, smart car search light module ?Features:? Photosensitive resistor module most sensitive to environmental light, generally used to detect the brightness of ambient light, triggering microcontroller or relay module; When ambient light intensity does not reach the threshold value, the module DO-side output high when the ambient light level exceeds the set threshold, DO terminal output low; DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the brightness of ambient light changes; DO output can directly drive the relay module, which can be composed of a light control switch. Analog output and AD module, through AD conversion, can obtain more accurate values of ambient light Pin Configuration:? VCC for positive power supply 3.3-5V GND for power supply is negative DO TTL switching signal output AO analogue signal output Package Includes: 1x 4Pin LDR Module Datasheet: 4Pin LDR Module Datasheet Related Products: SENSORS | MODULES
