Great for learning electronics
Bought this for a university robotics class. It's robust and handles voltage fluctuations well. The indicator LED helps a lot when debugging the circuit logic.

Perfect for my night light project
This module works exactly as described. The sensitivity adjustment is very smooth, allowing me to set the exact lux level where the switch triggers. Great build quality for the price.

Reliable sensor
I've used several of these in different rooms for automatic lighting control. They have been running for months without failure. Highly recommended for hobbyist home automation.

Solid performance
The response time is quick. I noticed a slight delay if the light change is very gradual, but that's typical for LDR sensors. Overall, a solid component for the kit.

Good value, easy to integrate
Integrated this with an ESP32 without any issues. The pinout is standard. Only giving 4 stars because the included jumper wires are a bit short, but the module itself is excellent.

Exceeded expectations
Very compact and fits perfectly into my custom 3D printed enclosure. The potentiometer stays in place once set, which is a nice touch compared to cheaper alternatives.
Q: Can this module directly drive a 12V LED strip?
A: No, this module outputs a low-voltage digital signal (3.3V/5V). You will need to use it to trigger a relay or a MOSFET transistor to safely control a 12V load.
Q: Is the sensitivity adjustable in both directions?
A: Yes, the onboard potentiometer allows you to adjust the threshold from very dark conditions to bright ambient light, giving you full control over the trigger point.
Q: What is the maximum current the output pin can source?
A: The output pin is designed for logic signaling and should not source more than 20mA. Please do not connect high-current devices directly to the output pins.
Q: Does this come with a library for Arduino?
A: Since it outputs a simple digital HIGH/LOW signal, no specific library is required. You can read the pin using the standard digitalRead() function in your Arduino sketch.
Q: Will this work outdoors in the rain?
A: The module itself is not waterproof. If you plan to use it outdoors, you must house it in a weatherproof enclosure with a clear window for the sensor.
