Works perfectly with Uno
Very sensitive and easy to calibrate using the potentiometer. Great for my light follower robot.

Good value for money
Does what it says. Pins were not pre-soldered which is standard, but good to note for beginners.

Great for learning
Used this in my university embedded systems class. Reliable readings in varying light conditions.
Q: Does it provide analog output?
A: This module outputs a digital signal. The DO pin goes high or low based on light threshold.
Q: What is the maximum current draw?
A: The module consumes approximately 10mA during operation.
Q: Is this compatible with Raspberry Pi?
A: Yes, it works with Raspberry Pi GPIO pins. Ensure you use the 3.3V logic level.
Q: Can I use this outdoors?
A: The PCB is not waterproof. It should be housed in a protective casing for outdoor use.
Q: Are headers included in the package?
A: Yes, a 3-pin male header strip is included for easy connection.
