Sensor Types Explained

Choose your sensor element

When designing a PIR sensor it is critical to choose the most appropriate pyro sensor. The type and model of sensor (Pyro) needs to be matched to the optical system so that the desired detection area is achieved and so that sensor is able to generate enough signal for detection to be successful.

Sensor Types Explained

We have a long history designing and manufacturing high performance lenses for PIR applications. We will carefully analyse your requirements and make a proposal how best to proceed with your project. Our engineers will consult with you and make a proposal concerning costs and development time.

For an indepth explanation of sensor types, please refer to this Excelitas document.
