Reliable light detection
I bought five of these for a garden lighting system. All five units performed consistently. The LM393 comparator provides a clean digital signal without any jitter, even in twilight conditions.

Good value, clear documentation needed
The hardware quality is solid and the soldering points are clean. It took me a moment to figure out which pin was AO vs DO without a diagram, but once connected, it functions perfectly. Great for the price.

Exceeded expectations
Very stable performance. I was worried about false triggers from indoor lighting fluctuations, but the hysteresis on the comparator handles it well. Definitely buying more for future projects.

Compact and efficient
Small footprint makes it easy to fit into tight enclosures. The analog output is linear enough for basic brightness logging, while the digital output is great for simple on/off logic. Highly recommended.

Perfect for my automatic night light project
This photodiode module worked exactly as expected. The sensitivity adjustment is very smooth, allowing me to set the exact lux level where the switch triggers. Used it with an Arduino Uno to control an LED strip, and the response is instant.

Great for learning sensors
Used this for my university electronics lab. It's very forgiving for beginners. The potentiometer makes it easy to visualize how threshold detection works. Only wish it came with header pins pre-soldered.
Q: Can this module be used directly with a 5V Arduino?
A: Yes, this module operates comfortably within the 3.3V to 5V range, making it fully compatible with standard 5V Arduino boards like the Uno and Mega.
Q: What is the difference between the 3-pin and 4-pin versions?
A: The 4-pin version typically breaks out VCC, GND, Digital Output (DO), and Analog Output (AO). The 3-pin version usually provides VCC, GND, and only the Digital Output, suitable for simple switch applications.
Q: Is the sensitivity adjustable for different lighting conditions?
A: Absolutely. There is an onboard blue potentiometer that allows you to fine-tune the detection threshold to suit anything from bright sunlight to dim indoor lighting.
Q: How do I connect this to a Raspberry Pi?
A: Connect VCC to the 3.3V or 5V pin, GND to ground, and the DO pin to a GPIO input. If using the Analog Output (AO), you will need an external ADC since Raspberry Pi GPIOs do not support analog input natively.
Q: Does this sensor detect infrared (IR) light?
A: This module uses a photodiode primarily sensitive to visible light. While it may have slight sensitivity to near-IR, it is not optimized for IR remote control signals; dedicated IR receivers are better for that purpose.
