IoT has made environmental monitoring & air pollution measurement more and more common. Our products are the fastest amongst both pyroelectric and thermopile technology, allowing higher resolution and ultra low power consumption. ezPyro™, the world’s first surface mount pyroelectric device is the smallest pyroelectric sensor available and is physically robust. Our customers have integrated them in a matter of weeks. For more sensitivity, our analog TO39 products provide high resolution and can go without recalibration for years.
New – upgraded analogue quad range with 4x larger pixel area
Pyreos is now sampling our new quad range which carries 4 x 1mm2 pixels. This provides much higher SNR and the product is mechanically vastly simpler and more robust than competing products. Datasheet download. As well as the list of quads in the table below, a new, more extensive list of filter combinations is available. The quad product range is expanding fast so if we do not list the you need then please contact us.
