Great for learning electronics
Used this for a university assignment on analog vs digital signals. It clearly demonstrates how light intensity affects resistance. The only minor issue is that the LED indicator is quite bright at night.

Reliable and sensitive
I bought five of these for a classroom setup. All units performed consistently. The LM393 comparator provides a clean digital signal, which is essential for reliable switching in our robotics kits.

Good value, clear instructions needed
The hardware quality is solid and the Dupont lines make connection easy. However, beginners might struggle slightly without a diagram explaining the difference between the DO and AO pins. Once figured out, it works great.

Compact and effective
Small form factor fits perfectly into tight enclosures. The photoresistor reacts quickly to changes in ambient light. Highly recommended for anyone building light-activated switches.

Exceeded expectations
For the price, you cannot beat this module. It includes both analog and digital outputs, giving flexibility in how you process the data. Shipping was fast and packaging protected the components well.

Perfect for my Arduino project
This sensor module works flawlessly with my Arduino Uno. The sensitivity adjustment via the potentiometer is very responsive, allowing me to set the exact light threshold needed for my automatic night light project.
Q: Is the sensitivity adjustable for outdoor use?
A: The potentiometer allows you to adjust sensitivity, but please note this module is not waterproof. For outdoor use, it must be housed in a weatherproof enclosure.
Q: What is the difference between the AO and DO pins?
A: AO (Analog Output) provides a variable voltage corresponding to the light intensity, while DO (Digital Output) gives a high/low signal based on a threshold you set using the onboard potentiometer.
Q: Does this come with jumper wires?
A: Yes, the package includes Dupont lines pre-attached or provided separately depending on the specific pin configuration (3-pin or 4-pin) you selected.
Q: How do I connect this to a Raspberry Pi?
A: Connect VCC to 5V or 3.3V, GND to Ground, and DO to a GPIO pin configured as input. If using AO, ensure you use an ADC chip since Raspberry Pi GPIOs do not support analog input natively.
Q: Can this module be used directly with a 3.3V microcontroller like ESP8266?
A: Yes, the module operates within a 3.3V to 5V range, making it fully compatible with 3.3V logic microcontrollers such as the ESP8266 and ESP32.
