Photosensitive sensor module light detection the photoresistor module, photosensitive module

Product Features Working voltage: 3.3V-5V VCC for Positive Supply 3.3-5V GND Negative DO TTL Switch Signal Output product description Module Features: Sensitive photosensitive resistance sensor Comparator output signal is clear, the waveform drive capacity better than 15mA. Adjustable potentiometer to detect light intensity adjustable Working voltage: 3.3V-5V Output format: digital switch output (0,1) With fixed bolt holes for easy installation Small PCB board size: 3.2cm x 1.4cm Use a wide woking voltage range LM393 comparator Applications: detection of light intensity, light intensity sensor, smart car searchlight module Module Description Photoresistor module is the most sensitive to ambient light, generally used for testing Ambient light brightness triggers microcontroller or relay module; When the ambient light intensity does not reach the threshold, the module DO side output high , 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, thus detecting changes in ambient light brightness; DO output can directly drive the relay module, which can be composed of light control switch. Product wiring instructions: For positive supply of VCC 3.3-5V power supply GND is negative DO TTL switch signal output Includes: 5 Photosensitive Sensor Modules
