Light intensity detected light level sensors, optical module Smart car search.
1 Using the sensitive type photosensitive resistance sensor
2 The comparator output signal clean waveform is good, driving ability, than 15mA.
3 With adjustable potentiometer can adjust the brightness of the light detected
4 Working voltage 3.3V-5V
5 The output format: Digital switching output (0 and 1)
6 With bolt holes for easy installation
7 A small board PCB size: 3.2cm x 1.4cm
8 Using a wide voltage LM393 comparator
Module for use:
1 The photosensitive resistor module most sensitive to ambient light, generally used to detect the brightness of the ambient light, triggering microcontroller or relay modules;
2 The module brightness of ambient light reach the set threshold, DO-side output high when the ambient light level exceeds the set threshold, DO-ended output low;
3 Do output can be directly connected with the microcontroller through the microcontroller to detect high and low, thereby detecting changes in ambient light intensity;
4 Do our outputs can directly drive the relay module, which can be composed of a light control switch.
