Photosensitive Sensor Module
Purpose:
Light brightness detection, light brightness sensor, intelligent car light search module
Module Features:
1. Adopt sensitive photoresist sensor
2. Comparator output, clean signal, good waveform, strong driving capacity, more than 15mA.
3. Equipped with adjustable potentiometer to adjust the detection light brightness
4. Working voltage 3.3V-5V
5. Output form: DO digital switch output (0 and 1) and AO analog voltage output
6. With fixed bolt holes for easy installation
7. Small PCB size: 3.2cm x 1.4cm
8. Use wide voltage LM393 comparator
Module Instructions:
1. The photosensitive resistor module is sensitive to the ambient light, and is generally used to detect the brightness of the ambient light, trigger the microcontroller or relay module, etc;
2. When the ambient light brightness of the module cannot reach the set threshold, the DO terminal outputs a high level; when the ambient light brightness exceeds the set threshold, the DO terminal outputs a low level;
3. The DO output end can be directly connected with the single chip computer to detect the high and low level through the single chip computer, thus detecting the change of the ambient light brightness;
4. The DO output terminal can directly drive the relay module of the store, thus forming a light-controlled switch.
5. Small board analog output AO can be connected with AD module. Through AD conversion, higher ambient light intensity can be obtained;
Product Wiring Instructions:
1. VCC is connected to the positive pole of power supply 3.3-5V
2. GND is connected to the negative pole of power supply
3. DO TTL switch signal output
4. AO analog signal output
