Product Description
The module uses a photoresistor based on the internal photoelectric effect, and its resistance decreases as the light intensity increases. It can be used to detect changes in the intensity of ambient light.
Features
- Designed with a high-quality double-sided PCB with power indication.
- Work voltage:3.3V-5.0V.
- The detection brightness can be adjusted
- Two output pins: Digital TTL (LOW / HIGH) and Analog output
- Using the LM393 comparator, it could output the perfect waveform and strong driving ability, the output current exceeds to 15mA
- When the ambient light brightness does not reach 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;
- The DO output end can be directly connected to the microcontroller, and the high and low levels are detected by the microcontroller to detect the change in the ambient light brightness;
- The Analog output can be connected to the analog input module, and the current light intensity value can be obtained by conversion
- PCB size: 32mm x 14mm
Typical applications
- Light brightness detection
- Smart car light-seeking module
