PYROELECTRIC DETECTORS FOR MOTION SENSING
Digital Pyrodetector
For Battery Operated Applications
PYD 1688, PYD 1698 – Low Power DigiPyro®
Target Applications
Intrusion Alarm, wireless
Battery operated Motion Detection
Features and Benefits
Wake up/ Sleep Mode
Low power consumption
Band pass included
Pulse count option
Product Description
The LowPower DigiPyro® is our latest introduction addressing the rquirements of further reduced
power consumption. With its further reduced current requirement at 3V supply the PYD 16 series
offers new programmable features: The Wake-up/Sleep mode enables to save unit power, making it
ideal for battery operated motion detection applications.
Continuous motion sensing, signal processing and event/motion detection is handled by the Low-
Power DigiPyro while the hosting microcontroller can be set into a power saving mode. Only upon
detection of a motion per its programmed settings, the LowPower DigiPyro signalizes the microcon-
troller to wake up.
Further options are selectable pulse count and electrical band pass.
The PYD 1688 /PYD 1698 include Dual Element Pyroelectric Detector design and the digital signal
processor, all built into a TO-5 housing..
