Perfect for my Arduino project
Works exactly as described. I used this to build a automatic night light and the sensitivity adjustment is very useful. Easy to wire up.

Good value but small
The module is quite small which is great for compact builds, but the pins are close together. Sensitivity is accurate enough for hobby use.

Reliable light detection
Used it for a garden sensor project. It handles outdoor ambient light changes well when protected in a case. Very stable output.

Potentiometer tricky
The sensor works, but the potentiometer was a bit stiff to turn initially. Took some time to calibrate the threshold correctly.
Q: Does it output analog values?
A: Yes, the AO pin provides an analog voltage proportional to light intensity, while DO provides a digital trigger.
Q: Can I use this with 3.3V logic levels?
A: Yes, the module operates comfortably within the 3.3V to 5V range, making it safe for most microcontrollers.
Q: Are headers pre-soldered?
A: This depends on the variant selected. Please check the product images or description for pinned vs. unpinned options.
Q: What is the detection range?
A: It detects visible light spectrum. The exact lux range depends on the potentiometer setting and ambient conditions.
Q: Can it power an LED directly?
A: The module output is a signal pin. You should use a transistor or relay module to drive high-power loads like LEDs.
