An ambient light sensor is a type of sensor that measures the amount of light in the surrounding environment. These sensors can be used in various applications, including lighting and backlighting control and ambient light sensing. It is also used in greenhouses to assess the exposure of plants to light and ensure they are getting enough light for optimal growth. Waterproof Digital Ambient Light Sensor Introduction
