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

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?
