Digital Pyroelectric Detectors
Digital Pyroelectric Detectors

Packing a great deal into a tiny package, ezPyro™ combines one or more pyroelectric sensor elements with a digital ASIC. Wavelength-specific sensing is achieved using factory configured optical filters. Configurable signal amplification, filtering and digitisation (ADC), as well as power management are all integrated in this, the smallest sensor of its kind.

The ezPyro™ SMD sensors come in several configurations, including single elements, dual elements and 2×2 arrays. Several application-specific filter options are available including for gases such as carbon monoxide (CO), carbon dioxide (CO2), Methane (CH4) and other hydrocarbons or nitric oxide (NO), or for detection of flames.
