Si114x IR Sensor ICs and Evaluation Boards

The QuickSense™ Si114x series ICs from Silicon Labs are the industry’s most sensitive and lowest power active infrared proximity and ambient light sensor ICs. The monolithic Si114x family of devices features an all digital I²C control interface and up to three infrared LED drivers in an impressively small 2 mm x 2 mm clear QFN package. Capable of controlling one, two, and three infrared LED systems, developers have the freedom to implement one-dimensional systems with a range of up to 50 cm or multi-dimensional systems capable of advanced motion sensing with a range of up to 15 cm. The robust infrared sensing architecture works in direct sunlight and includes an ambient light sensor capable of sensing light levels up to 128 kLux.
