Description
Photosensitive Sensor Module 4 Pins 3.3-5V Light Dependent Resistor Sensor Module Digital Light Intensity Detection LM393 for ArduinoSIZE：Length:0.55inch/14mmWidth: 1.22inch/31mmWiring method:VCC: Connect to the positive pole of the power supply (3-5V)GND: Connect to the negative pole of the power supplyDO: TTL switch signal outputAO: Analog signal output (different voltages are output at different distances, this pin generally does not need to be connected)Features:⚪It can detect the brightness and light intensity of the surrounding environment (compared to photoresistors, it has better directionality and can sense light sources in a fixed direction)⚪Adjustable sensitivity (blue digital potentiometer adjustment in the figure)⚪Sensitive photoresistive sensors are used⚪It is equipped with an adjustable potentiometer to adjust the brightness of the detection lightWorking voltage:3.3V-5VOutput Form: 1.digital switching output (0 and 1) 2.AO analog voltage outputEquipped with fixing bolt holes ：easy installationUse wide voltage LM393 comparatorStrong drive capacityThe signal is cleanThe waveform is goodWorking Current: 15mAInstructions for use of the module:1. The photoresistor module is sensitive to ambient light, and is generally used to detect the brightness of the light in the surrounding environment, trigger the single-chip microcomputer or relay module, etc.;2. When the ambient light brightness of the module does not reach the set threshold, the DO terminal outputs a high level, and when the external ambient light brightness exceeds the set threshold, the DO terminal outputs a low level;3. The DO output terminal can be directly connected to the single-chip microcomputer, and the high and low levels can be detected through the single-chip microcomputer, so as to detect the change of light brightness in the environment;4. The DO output terminal can directly drive the relay module of the store, so that a light control switch can be formed.5. The analog output AO of the small board can be connected to the AD module, and through the AD conversion, a more accurate value of the ambient light intensity can be obtained;Place of Application:·Light brightness detection·Light brightness sensor·Intelligent car light-finding modulePackage contains:3Pcs Photosensitive Sensor Module
