XV0060 Module cảm biến quang trở 3 chân Mô tả: Uses: • Light intensity detected light intensity sensor, smart car search light module • Module Features: 1, using sensitive photosensitive resistance sensor • the comparator output signal is clean, good waveform, driving ability, more than 15mA. • with adjustable potentiometer to adjust the brightness of the light detection • the working voltage 3.3V-5V • the output form: DO digital switching outputs (0 and 1) and AO analog voltage output • a fixed bolt holes for easy installation • a small PCB board size: 3.2cm x 1.4cm • using a wide voltage LM393 comparator Module for use • the photosensitive resistor module most sensitive to ambient light, generally used to detect the brightness of ambient light, triggering microcontroller or relay modules; • the module when the brightness of ambient light can not reach the set threshold, DO-side output high when the ambient light level exceeds the set threshold, DO end 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 to change; • DO output of the relay module can directly drive the shop, which can be composed of a light control switch. Product wiring instructions: • VCC positive power supply 3.3-5V • GND power supply is negative DO TTL switching signal output
