QFS series I2C-SMD pyroelectric infrared flame sensors

KEMET has launched QFS series I2C-SMD pyroelectric infrared flame sensors

KEMET QFS Series I2C-SMD Pyroelectric Flame Sensors

KEMET’s QFS pyroelectric flame sensors combine high sensitivity with fast response times and high dynamic range to ensure rapid and accurate detection of small and large flames, nearby or over larger distances. These high quality sensors, in their small SMD package, integrate a digital, current mode read-out offering high responsivity over the full frequency range of flame flicker from 3 – 30 Hz. Industry standard I2C communication enables plug-and-play connectivity to microcontrollers and allows easy tuning and calibration. Programmable gain and filtering offer maximum flexibility in system design, and various optical filter options are also available. These sensors can be connected toegther in linear series to allow synchronized sampling across devices. Their long and maintenance-free operational lifetime and various low power modes makes it ideal for any smart or IoT type of applications.
