Great for students
Bought these for my robotics class. Students found them easy to interface with microcontrollers. Durable enough for repeated use.

Perfect for my Arduino lamp
Works flawlessly with my Arduino Uno. The sensitivity adjustment potentiometer makes it easy to set the trigger point. Included wires were a nice bonus.

Needs calibration
Works okay but took some time to calibrate the potentiometer correctly. Once set, it stays consistent. Good for the price.

Highly sensitive
I was impressed by how quickly it reacts to changes in light. Using it for a automatic night light project. Very stable output.

Good value sensor
Does exactly what it says. I deducted one star because the soldering points are a bit small for beginners, but otherwise great module.
Q: Can I use this with Raspberry Pi?
A: Yes, it is compatible with Raspberry Pi GPIO pins when configured for 3.3V logic levels.
Q: How do I adjust the sensitivity?
A: There is a blue potentiometer on the board. Turn it clockwise or counter-clockwise to adjust the light threshold.
Q: What is the length of the Dupont wires?
A: The included Dupont wires are approximately 20cm in length, suitable for breadboard connections.
Q: Does this work with 3.3V logic?
A: Yes, the module supports operating voltages between 3.3V and 5V DC.
Q: Is the output analog or digital?
A: This module provides a digital switching output (TTL). For analog readings, you would need a different sensor type.
