PYD 1588 / 7656
Low Power Dual Element Pyro
The PYD 1588 is a serial opposed format, two elements detector based on
pyroceramic. The signal is converted to a digital value using Sigma-Delta and
DSP techniques. A congurable motion detection unit is implemented. Once
motion was detected, an interrupt will be send to the host system. Putting the
host system to sleep an overall ultra low power consumption will be achieved.
All data is accessible from the host system to enable advanced signal analysis
with your own detection criteria. Excelitas digital solutions provide excellent
EMI immunity.
