3pin photosensitive sensor module

Discription
• 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
