Great for learning electronics
As a beginner, this was an excellent component to understand how analog sensors can be converted to digital signals. The included Dupont lines made connecting to my breadboard super easy.

Exceeded expectations
Very sensitive and accurate. I was able to detect subtle changes in room lighting for my smart home automation setup. Highly recommend for DIY enthusiasts.

Good value, clear instructions needed
The sensor itself is great and responds quickly to light changes. I deducted one star because it didn't come with a printed pinout diagram, but a quick online search solved that.

Perfect for my Arduino project
This module worked flawlessly right out of the box. The sensitivity adjustment via the potentiometer is very precise, allowing me to set the exact light threshold needed for my night lamp project.

Solid performance
We used these in a high school robotics competition. They held up well under stress. Just make sure to calibrate them in the actual environment where they will be used.

Reliable and compact
I bought five of these for a garden lighting system. They are small, easy to mount, and the LM393 chip ensures stable output signals even with fluctuating power.
Q: Can this sensor detect infrared light?
A: This is a standard photoresistor module designed primarily for visible light detection. It is not optimized for specific infrared wavelengths.
Q: Are the Dupont lines male-to-male or female-to-female?
A: The included Dupont lines are typically Female-to-Male, designed to connect the module's male header pins to a breadboard or microcontroller.
Q: Can this module be used directly with a 3.3V microcontroller?
A: Yes, the operating voltage range is 3.3V to 5V DC, so it is fully compatible with 3.3V systems like the ESP8266 or ESP32.
Q: What is the maximum current this module draws?
A: The module consumes very little power, typically around 10-15mA when active, making it suitable for battery-powered projects.
Q: Does the output signal stay high when it is dark or when it is light?
A: The default output logic can be inverted by adjusting the potentiometer. Typically, you can configure it so the output goes LOW when light is detected and HIGH when it is dark, or vice versa.
