Good sensitivity
Detects light changes well. Would prefer a digital output pin onboard too, but for the price, the analog output is sufficient.

Reliable module
Using it for automatic night light project. Very stable readings over the past month. No issues with voltage drops.

Needs calibration
Works but had to adjust the potentiometer for my specific lighting conditions. Readings were a bit noisy initially.

Perfect for Arduino Projects
Works flawlessly with my Uno. The analog output is smooth and easy to read using standard analogRead functions. Great value for money.
Q: What is the detection range in Lux?
A: It detects visible light intensity relative to voltage output. Specific Lux values depend on calibration.
Q: How many pins does the connector have?
A: Typically 3 pins: VCC, GND, and Signal Out. Some versions may include a digital output pin.
Q: Does it come with specific libraries?
A: No, but standard analog read functions work perfectly. No special library is required.
Q: Can I use this with 3.3V logic boards?
A: Yes, it operates comfortably between 3.3V and 5V DC, making it safe for most microcontrollers.
Q: Is this module waterproof for outdoor use?
A: No, this module is for indoor or protected enclosure use only. It is not water-resistant.
