QMS Motion and Gesture Sensors

KEMET's QMS thin-film digital pyroelectric IR sensors combine high sensitivity with fast response times to ensure rapid and accurate motion detection, as well as a high dynamic range to allow motion detection nearby or over larger distances. The 2x2 pixel version of this device allows users to determine the direction of motion.

These high-quality sensors integrate a digital current-mode readout in a small SMD package. Industry-standard I²C communication enables plug-and-play connectivity to microcontrollers and allows for easy tuning. Programmable gain and filtering offer maximum flexibility in system design, and various low-power modes are also available, including a wake-up by motion feature. These sensors can be connected in linear series to allow synchronized sampling across multiple devices.
