Good quality, easy to interface
I used this with an Arduino Uno for a light-activated night lamp project. Wiring was straightforward, and the digital output is clean. Only wish the mounting holes were slightly larger.

Perfect for my line-following robot
This sensor module works exactly as described. The sensitivity adjustment is very smooth, allowing me to calibrate it perfectly for indoor lighting conditions. Great value for the price.

Solid performance
Works well for detecting ambient light changes. The potentiometer allows fine-tuning which is crucial for avoiding false triggers in varying environments.

Great addition to my parts bin
Bought five of these for a smart home automation prototype. All units performed identically. Fast shipping and well-packaged.

Reliable and sensitive
The LM393 comparator provides stable switching. I tested it under various light sources, and it responded consistently. Highly recommended for student projects.

Excellent for beginners
Clear labeling on the PCB makes it easy to connect VCC, GND, and DO. The tutorial examples online work flawlessly with this specific module.
Q: Can I use this directly with a 3.3V microcontroller like ESP32?
A: Yes, the operating voltage range is 3.3V to 5V, making it fully compatible with 3.3V logic systems like the ESP32, ESP8266, and Raspberry Pi without level shifters.
Q: What is the maximum current this module can handle?
A: The module itself draws very little current (typically around 10-20mA). The digital output pin can source/sink up to 15mA, which is sufficient for driving standard logic inputs or small indicator LEDs.
Q: Can this module detect infrared light or only visible light?
A: This photoresistor module is primarily sensitive to visible light. It is not optimized for infrared detection; for IR applications, we recommend our dedicated IR receiver modules.
Q: Does this come with header pins soldered?
A: No, the module ships with a separate strip of header pins to allow you to solder them yourself or use jumper wires directly, giving you flexibility in mounting.
Q: Is the analog output (AO) pin available on this version?
A: This specific model features a digital output (DO) only, utilizing the LM393 comparator. If you require raw analog values, please check our 'Analyze Photoresistor' product listing.
