The pyroelectric effect that our devices exploit is particularly effective at flame detection, that effect harnessed by our unique patented technology delivers a flame detection sensor range with exceptional responsivity and range, enabling the development of market leading flame detection systems.
Now field-proven in gunshot, gunfire and muzzle flash detection systems. See Gunshot Applications Page, Gunshot News Release

We offer flame detection across our entire range, in either an SMD or TO-39 packaged devices and with a digital or analogue output. These different form factors offer different strengths: ezPyro TO offers best sensitivity and range, and faster development in the digital ecosystem; ezPyro SMD offers smallest footprint and is most cost-effective; Both ezPyro products are integrated systems offering minimum component count.
Analog TO offers optimum performance and instand start-up in a traditional analog environment. All systems offer class-leading speed and fast start-up. Demonstrated ranges with no extra optics range from 35m to 90+m depending on test conditions.
By also offering companion sensors to the main flame detecting sensor it is possible to refine a flame detection system to operate in challenging environments such as in high-levels of human motion, sunlight and arc welding, enabling a reliable system tuned to reject false positives.
