Excelitas’ PYD 1598 is a serial opposed format, two elements detector based on pyroceramic. The signal is converted to a digital value using sigma-delta and digital signal processing (DSP) techniques. A configurable motion detection unit is implemented. Once motion is detected, an interrupt is sent to the host system. Putting the host system to sleep, an overall ultra-low power consumption is achieved. All data is accessible from the host system to enable advanced signal analysis with the user’s detection criteria. Excelitas digital solutions provide excellent electromagnetic interference (EMI) immunity.
