Light Sensitive Resistance Sensor

Description

Light brightness detection, light brightness sensor, smart car light search module
Module characteristics:
1. Adopt a sensitive light-sensitive resistance sensor
2. The output of the comparator, the signal is clean, the waveform is good, and the driver capacity is strong, more than 15mA.
3. Match the adjustable detection light brightness
4. Work voltage 3.3V-5V
5. Output form: Digital switching output (0 and 1)
6. There are fixed bolt holes for easy installation
7. Small board PCB size: 3.2cm x 1.4cm
8. Use width voltage LM393 comparator
Module use instructions
1. The optical resistance module is sensitive to the environmental light. It is generally used to detect the brightness of the light of the surrounding environment, trigger the single-chip microcomputer or relay module, etc.;
2. When the brightness of the module does not reach the set threshold, the DO end outputs a high level. When the external environment of the external environment exceeds the set threshold, the DO end outputs a low level;
3. The DO output terminal can be directly connected to the single-chip microcomputer and the high and low levels are detected by a single-chip machine.
4. The DO output terminal can directly drive the relay module of the shop, which can form an optical control switch.
