Description
low power DigiPyroTM
Infrared Sensing Solutions 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 configurable 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.
