Great for beginners
As someone new to electronics, this module was easy to integrate. The included Dupont lines saved me time, and the output LED makes debugging very simple.

Perfect for my Arduino project
This sensor module works flawlessly with my Arduino Uno. The sensitivity adjustment is very responsive, allowing me to set the exact light threshold I needed for my automatic night light project.

Good value, clear instructions needed
The hardware quality is solid and the LM393 chip is reliable. It took me a moment to figure out the pinout without a diagram, but once connected, it detected light changes instantly.

Reliable and consistent
I bought ten of these for a classroom kit. All units performed consistently with no dead-on-arrival sensors. The detection range is adequate for indoor lighting conditions.

Excellent sensitivity control
The ability to fine-tune the trigger point with the onboard potentiometer is fantastic. I used this for a solar tracker prototype and it responded quickly to shadow changes.

Solid performance
Works exactly as described. The only reason for 4 stars instead of 5 is that the potentiometer feels a bit stiff, but it functions correctly once adjusted.
Q: Does this module output analog or digital signals?
A: This specific module outputs a digital signal (HIGH or LOW) based on the light threshold you set. If you need analog values, please look for our LDR analog sensor variant.
Q: Can I connect this directly to a 5V Raspberry Pi GPIO?
A: Yes, the module operates on 3.3V to 5V, making it compatible with Raspberry Pi GPIO pins. Just ensure you connect the VCC to the 5V or 3.3V pin and GND to ground.
Q: Are the Dupont lines included in the package?
A: Yes, the package includes a set of Dupont jumper wires to help you get started immediately with your breadboard or microcontroller.
Q: What is the maximum current this sensor can switch?
A: The LM393 comparator output is designed for logic level signaling, not for driving high-power loads directly. Please use a transistor or relay module if you need to switch higher currents.
Q: How do I adjust the sensitivity?
A: There is a blue potentiometer on the board. Use a small screwdriver to rotate it clockwise or counter-clockwise while exposing the sensor to your target light condition until the output LED toggles.
