Optical sensors are devices that detect and measure electromagnetic radiation in the visible, ultraviolet and infrared ranges. These sensors work by converting light or illumination into an electrical output. One type of optical sensor is ambient light, IR, and UV Sensors and amongst these sensors, TSL26711FN is a popular choice.

The TSL26711FN is an ambient light, IR, and UV sensor. It is a low power consuming light-to-digital converter with 2 IR LEDs and enables the sampling of ambient light intensity for use in determining a display backlight intensity level. It features a programmable interrupt that provides the capability to set comparison level of visible, IR, and ultraviolet light for automatic dimming control. It also enables synchronization via PWM inputs with an on-board digital filter. The operating range of this sensor is 0.2 to 30,000 lux for visible and 0.5 to 18,000 wm-2 for IR.

The working principle of the TSL26711FN is based on its two internal photodiodes; one for visible light and one for infrared. These photodiodes convert the light into an electrical current which is then filtered and digitized. The TSL26711FN also features a programmable interrupt which provides the capability to set a comparison level between visible, IR, and ultraviolet light, this enables automatic dimming control. On-chip digital filtering also helps reduce flicker and ripple effects. The datasheet for this device can be found on the manufacturer’s website and provides details on all of its features and specifications.

The TSL26711FN has a wide variety of applications. It is commonly used in portable devices such as cell phones, tablets, digital cameras, and other consumer electronics. It can be used to measure light levels for automatic backlighting, and for display contrast control, ambient light sensing, and proximity sensing. The TSL26711FN is also ideal for solar cell and solar panel applications, where it can be used to measure the level of intensity of light from the sun.

In summary, the TSL26711FN is a popular choice for ambient light, IR, and UV sensors. It is a low power consuming light-to-digital converter with two photodiodes ensuring accurate light measurement. The device also features a programmable interrupt for comparison level setting between visible light, IR, and ultraviolet light. Its wide applications span consumer electronics, solar cell and panel applications, and other light measurement tasks.
