Perfect for Arduino Projects
This module works flawlessly with my Arduino Uno. The sensitivity adjustment is very smooth, allowing me to set the exact light level needed to trigger the switch. Great value for the price.

Bulk buy success
Purchased a lot for our community workshop. Every single module worked out of the box. The dual output (analog and digital) makes it versatile for different skill levels.

Exactly as described
Fast shipping and the product matches the description perfectly. The analog output gives a nice range of values for more complex logic, not just simple on/off switching.

Good sensitivity, clear instructions
The photodiode reacts quickly to changes in light. I used it for a night light project. Only giving 4 stars because the soldering pads are a bit small for beginners, but otherwise excellent.

Reliable and Compact
I bought five of these for a line-following robot variation that detects light zones. All units performed consistently. The compact size makes it easy to fit into tight chassis designs.

Great for learning sensors
Used this in my university embedded systems lab. It's robust enough to handle student errors and provides clear readings. The potentiometer is a bit stiff initially but loosens up with use.
Q: Can this module be directly connected to a 5V Raspberry Pi GPIO?
A: Yes, the module operates on 3.3V to 5V. However, ensure you connect the DO pin to a GPIO pin configured for input. If using the analog output (AO), note that Raspberry Pi requires an external ADC since it lacks native analog inputs.
Q: What is the maximum distance this sensor can detect a light source?
A: The detection range depends heavily on the intensity of the light source and ambient conditions. For a standard LED indicator at room lighting, it typically detects within 5-15cm. It is designed for proximity light detection rather than long-range.
Q: Does this come with header pins pre-soldered?
A: No, the module is shipped without header pins soldered to provide flexibility for direct wire soldering or using your own headers. You will need to solder them yourself.
Q: Is the output active high or active low?
A: The digital output (DO) is typically active low, meaning it outputs LOW (0V) when light is detected and HIGH (VCC) when dark, though this can sometimes depend on specific circuit variations. We recommend testing with a multimeter upon arrival.
Q: How do I adjust the sensitivity threshold?
A: There is a blue potentiometer on the back of the PCB. Rotate it clockwise to increase sensitivity (trigger in dimmer light) or counter-clockwise to decrease it. Use a small screwdriver while monitoring the signal LED.
