Perfect for Classroom Projects
I bought a dozen of these for my high school robotics club. They are incredibly easy to wire up with standard jumper cables and work flawlessly with our Arduino kits. The students were able to build light-following robots in just one session.

Solid build quality
The PCB looks clean and the soldering points are well-made. I've tested the analog output values, and they are consistent across different lighting conditions. Highly recommended for any maker working on environmental sensing projects.

Fantastic learning tool
My daughter used this to learn how analog sensors work. Being able to see the numbers change in the serial monitor as she waved her hand over it was a great 'aha!' moment. Durable enough to handle curious kids.

Great value, sensitive detection
Very responsive to changes in light. My son used it to make a night-light that turns on automatically when the room gets dark. The only reason for 4 stars is that the included documentation was a bit sparse, but we found plenty of tutorials online.

Easy for beginners
As someone new to electronics, I was worried about compatibility. This module plugged right into my starter kit breadboard without any issues. The code examples provided on the manufacturer's site worked immediately.

Good for prototyping
Works exactly as described. It's not industrial grade, but for educational purposes and rapid prototyping, it is excellent. The response time is fast enough for most line-following or light-tracking applications.
Q: What is the maximum distance it can detect a light source?
A: This is an ambient light sensor, not a proximity sensor. It measures the intensity of light falling directly on the photoresistor rather than detecting a specific light source at a distance. Performance depends on the brightness of the environment.
Q: Is there a digital output pin available on this board?
A: This specific model provides an analog output (AO) which gives a continuous range of values based on light intensity. It does not have a built-in comparator for a digital output (DO), but you can easily set a threshold in your code.
Q: Can this be used with a 3.3V microcontroller like the ESP32?
A: Yes, absolutely. The operating voltage range is 3.3V to 5V, making it fully compatible with 3.3V logic boards like the ESP32, ESP8266, and 3.3V Arduino variants.
Q: Does this module come with the connecting wires?
A: No, the module is sold separately. However, it uses a standard 3-pin interface compatible with most generic Dupont jumper wires commonly found in electronics starter kits.
Q: Are driver libraries required to use this?
A: No special libraries are needed. Since it outputs a simple analog voltage, you can read it using the standard 'analogRead()' function available in the Arduino IDE and similar environments for other microcontrollers.
