Perfect for Arduino Projects
This sensor module works flawlessly with my Arduino Uno. The analog output gives smooth readings for light intensity, and the digital threshold is easy to adjust with the onboard potentiometer. Great value for the price.

Does exactly what it says
Simple plug-and-play functionality. I connected it to a 5V relay module to control a lamp based on ambient light, and it switched perfectly at dusk. The adjustment screw allows for precise tuning.

Great for classroom kits
We use these in our robotics workshop. They are durable enough for students to handle and solder. One unit had a slightly loose header pin, but it was an easy fix. Overall, a solid educational tool.

Excellent Analog Response
The analog output voltage scales linearly with light intensity in my testing environment. It made calibrating my data logging script very straightforward. No noise issues observed.

Good sensitivity, clear instructions needed
The photodiode is very sensitive and reacts quickly to changes in light. I wish it came with a printed pinout diagram, but I found the details online easily. Works great for my automatic night light project.

Reliable and Compact
I bought five of these for a home automation system. All of them performed consistently. The form factor is small enough to fit into tight enclosures. Highly recommended for hobbyists.
Q: How do I calibrate the sensitivity for my specific room lighting?
A: Use a small screwdriver to turn the blue potentiometer on the board while monitoring the DO pin or the status LED. Turn it until the output switches at your desired light level.
Q: Is the photodiode sensitive to infrared light or only visible light?
A: The photodiode is primarily sensitive to visible light, though it may have some minor response to near-infrared wavelengths. It is optimized for general ambient light detection applications.
Q: What is the difference between the DO and AO pins?
A: The AO (Analog Output) pin provides a continuous voltage proportional to the light intensity. The DO (Digital Output) pin acts as a switch that goes high or low when the light level crosses the threshold set by the potentiometer.
Q: Does this come with jumper wires included?
A: No, the package includes only the sensor module itself. Jumper wires and headers need to be purchased separately if you do not already have them.
Q: Can this module be used directly with a 3.3V microcontroller like ESP32?
A: Yes, the module supports an operating voltage range of 3.3V to 5V, making it fully compatible with 3.3V logic systems like the ESP32 or ESP8266 without needing a level shifter.
