Ambient Light Sensors

Ambient Light Sensors can be used whenever a high resolution light sensor with a two-wire digital interface is required. Applications include street light control, security lighting, sunlight harvesting, machine vision, automotive instrumentation clusters.

Display management, or controlling the display brightness depending on the lighting environment, can benefit products such as handheld instruments, data loggers, notebooks, tablets, flat-panel televisions, cell phones, and digital cameras. Ambient Light Sensing offers up to 30% in energy saving - reducing power consumption, extending battery life and improving picture quality.

Ambient light sensors from Excelitas provide an easy solution for applications that require a response similar to the human eye, making it ideal when the response should only be influenced by visible light. There are three main devices types: filtered photodiodes, filtered phototransistors and wavelength selective devices based on III-V material. They are available in a number of standard packages, including surface mount for automated assembly.

VTP, VTB and VTT Ambient Light Sensors

Ambient Light Sensors from Excelitas are spectrally adapted photodiodes and phototransistors, featuring Excelitas' IR-BLOC technology to give a response approaching that of the human eye.

There are three main devices types, one being filtered photodiodes, the second filtered phototransistors and finally wavelength selective devices based on III-V material.

They are available in a number of standard packages, including surface mount for automated assembly.
