This waterproof digital ambient light sensor is designed to deliver accurate measurements of light intensity within the range of 1-65535 lx. It incorporates a 50Hz/60Hz light noise rejection function, ensuring stable and reliable performance. With an easy-to-use Gravity interface and I2C communication, the ambient light sensor is incredibly user-friendly for use with microcontrollers like the Arduino UNO. Plus, the sensor features an IP68 waterproof rating, which means it can be fully immersed in water without suffering any damage. This makes it perfect for outdoor projects that require reliable light measurement in harsh environments, such as vegetable greenhouses, smart car lights, and weather stations.
