Photosensitive Sensor Module/ Resistor Module Be Able to Adjustable Detection Light Brightness and Have Clean Driving Ability |

• 1. The photoresistor module is most sensitive to ambient light, and is generally used to detect the brightness of the surrounding environment, triggering a single-chip or relay module;
• 2. When the ambient light brightness reaches the set threshold, the DO end outputs a high level. When the ambient light brightness 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-low level is detected by the single-chip microcomputer, thereby detecting the change of the light brightness of the environment;
• 4. The DO output can directly drive the relay module of the store, which can form a light control switch.
•  

• 1. Using sensitive photoresistor sensor
• 2. Comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA.
• 3. With adjustable potentiometer can adjust the detection light brightness
• 4. Working voltage 3.3V-5V
• 5. Output form: digital switch output (0 and 1)
• 6. With fixing bolt holes for easy installation
• 7. Small board PCB size: 3.2cm x 1.4cm
• 8. Use wide voltage LM393 comparator
