Reliable for classroom kits
We bought a bulk pack for our workshop. All units tested working out of the box. They are robust enough to handle being plugged and unplugged by students repeatedly.

Works as described
Does exactly what it says on the tin. Detects light changes accurately. The LED indicator on the board is helpful for debugging without needing a multimeter.

Excellent sensitivity range
I was impressed by how wide the adjustment range is on the potentiometer. You can tune it to detect very subtle changes in light or only strong shadows. Highly recommended.

Perfect for Arduino Projects
This sensor module works flawlessly with my Arduino Uno. The sensitivity adjustment potentiometer makes it very easy to calibrate for different lighting conditions. Great value for the price.

Easy to use for beginners
As a student new to electronics, I found this module very straightforward to connect. The digital output simplifies the coding process significantly compared to reading raw analog values.

Good quality, fast shipping
The build quality is solid and the LM393 chip is genuine. I used four of these for a line-following robot and they all performed consistently. Only minor issue was the headers were not pre-soldered.
Q: Can this detect infrared light?
A: The photoresistor is primarily sensitive to visible light. While it may have some minor response to near-infrared, it is not optimized for IR detection. For IR, we recommend our dedicated IR receiver modules.
Q: What is the maximum current consumption of this sensor?
A: The typical current consumption is around 10mA to 15mA when the onboard LED is active. If you need to save power, you can desolder the power LED resistor.
Q: Does this output an analog signal or just digital?
A: This specific module outputs a digital signal (HIGH/LOW) based on the threshold set by the potentiometer. It does not provide an analog voltage output proportional to light intensity.
Q: Is the header pin strip included in the package?
A: Yes, the package includes a 3-pin header strip, but it is not pre-soldered to the board. You will need to solder it yourself or use jumper wires with breadboards.
Q: Can this module be used directly with a Raspberry Pi GPIO?
A: Yes, since the module operates at 3.3V to 5V and provides a digital output, it is compatible with Raspberry Pi GPIO pins. Just ensure you connect the VCC to the 3.3V or 5V pin accordingly.
