The TSL25911 sensor has a sensitivity of 188µLux. You can also find multiple bypass capacitors used to eliminate any noise in the supply.Ĭommonly Asked Questions What is the sensitivity of the TSL25911 sensor? The TSL25911 sensor module has only very few components, which include the TSL25911FN AMS chip itself along with the voltage regulator and the level shifter circuit.

So, in this Arduino interfacing tutorial series let’s look at such a sensor module built around the TSL25911 light sensor. Dimming the screen on a mobile device also prolongs the lifetime of the battery. This avoids having the screen be too bright when the user's pupils are adapted for vision in a dark room, or too dim when the device is used outdoors in the daytime. The amount of light is measured by such devices and the screen brightness is adjusted proportionally to the ambient light. The perfect example of such a scenario is the auto-brightness control of our smartphones or laptops. But you can find much more advanced types of light sensors being used in automatic lighting systems for smartphones and other smart devices. Detecting the amount of light in the ambiance is necessary for many areas of our everyday life, and the sensors which can do this are called light sensors, the most primitive light sensor is a humble LDR.
