KEMET’s lineup of environmental sensors detect the condition of the environment and can be used to alert safety monitoring systems of changes in conditions. These sensors are based on the pyroelectric effect that make them lower in power consumption than traditional silicon-based sensors. Similar to how the piezoelectric effect converts mechanical energy to electrical energy when a crystalline lattice is disturbed, the pyroelectric is a crystalline lattice that converts blackbody thermal energy to electrical energy. These sensors are available in both digital and analog interfaces and address various requirements of detecting or monitoring applications.

Flame Detection
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 together in a linear series for synchronized sampling across devices. Their long and maintenance-free operational lifetime and various low power modes make these sensors ideal for any smart or IoT type of applications.

KEMET’s QFC pyroelectric flame sensors provide accurate discrimination of flame sources in triple IR flame detection systems, through their excellent signal to noise characteristic at the signature 8 – 10 Hz flicker range of a flame. The sensor element is built into a low noise circuit that has an internal CMOS op amp with a 10 GΩ feedback resistor outputting a voltage signal centered around half the supply rail. Exceptionally high responsivity, a wide field of view and rapid recovery from thermal and electrical shocks makes it the ideal solution for demanding flame detection applications.

KEMET’s QDA line sensor arrays, or linear arrays, utilize unique thin-film pyroelectric PZT material to offer outstanding resolution and performance across a wide infrared wavelength range. The ASIC readout electronics output is a multiplexed, amplified, and filtered analog signal for each sensor element. The sensor is housed in a low-profile sealed metal package along with a temperature sensor and can be fitted within a choice of filter windows. An additional “+1” sensor element can provide higher sensitivity on a discrete wavelength, typically for lubrication oil or foodstuffs. This +1 sensor is located for ATR and transmission use.
