Light Sensitive Resistance Sensor

<p>Light brightness detection, light brightness sensor, smart car light search module<br />
Module characteristics:<br />
1. Adopt a sensitive light-sensitive resistance sensor<br />
2. The output of the comparator, the signal is clean, the waveform is good, and the driver capacity is strong, more than 15mA.<br />
3. Match the adjustable detection light brightness<br />
4. Work voltage 3.3V-5V<br />
5. Output form: Digital switching output (0 and 1)<br />
6. There are fixed bolt holes for easy installation<br />
7. Small board PCB size: 3.2cm x 1.4cm<br />
8. Use width voltage LM393 comparator<br />
Module use instructions<br />
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.;<br />
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;<br />
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.<br />
4. The DO output terminal can directly drive the relay module of the shop, which can form an optical control switch.</p>
