Perfect for Arduino Projects
Works exactly as described. Easy to calibrate with the potentiometer. I used it for a night light project and it triggers reliably.

Reliable Sensor
Very stable output. Using it for a line follower robot light detection system. No false triggers so far.

Good but needs tuning
Works well once you adjust the sensitivity. Instructions could be clearer for beginners, but online tutorials help.

Great Value
Bought five for a home automation project. All working perfectly. The sensitivity adjustment is very responsive.
Q: Does it output analog or digital signals?
A: This module outputs a digital signal (HIGH/LOW). For analog readings, use the photoresistor directly.
Q: Can I use this sensor outdoors?
A: It is not waterproof. We recommend using a protective enclosure for outdoor applications.
Q: What is the effective detection range?
A: Range depends on ambient light and sensitivity setting, typically effective within close proximity.
Q: How much current does the module draw?
A: The module draws approximately 10mA when active, which is safe for most GPIO pins.
Q: Is this compatible with 3.3V logic levels?
A: Yes, it operates between 3.3V and 5V DC, making it suitable for most microcontrollers.
