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.
Typical pyro sensor types
A variety of pyro sensors are available from several manufacturers. Carclo has lenses to support most common sensors.

Please note sensor height
** For some lenses the optical distance is critical-
Beware of Pyro Sensor orientation!
