Review on CQRobot Ocean: TSL25911FN Ambient Light Sensor for Raspberry Pi, Arduino, and STM32. Wide 0-88000Lux Detection Range, 600M:1 for Industries, Mobile Phones, Computers, Lighting, GPS, and More. by Justin Butler

This light sensor comes pre-wired and easily connects to a Raspberry Pi, Arduino or other small board to add light detection to your project. Great for turning on lights from dawn to dusk, or spotting things like opening a dark closet. This sensor board has a million uses. As well as simple light detection, it can measure the amount of light, which can be useful for adjusting an artificial light source based on the ambient light in a given area. The pins are clearly marked and the wire connects directly to the connector pins for easy connection. The board offers 2 mounting holes for permanent installation, and it would be easy to 3D print a small case for a professional look. Good quality environmental sensor board and there is a lot of information on the internet on how to integrate this TSL25911FN light sensor chip into your Arduino or RP project.
