Next-Generation, Low-Power
for Battery-Operated Motion Detection
PYD 1588, PYD 1598 – PYQ 1548
The new Low-Power DigiPyro “Gen2” 1500 Series is the upgrade
from our PYD 1600 Series which was introduced with great success
in 2015. The new generation DigiPyro addresses the growing
market requirements for added performance and functionality.
With significant reduction of supply voltage requirements, the
PYD 1500 Series operates at 1,8 V – 3,3V. Further, the new Low-
Power DigiPyro “Gen2” offers selectable band-pass function, and
improved selectable pulse count extending affect detection range
and minimizing sensor reaction time.
The wake-up / sleep mode promotes power savings and extends
service life, making it ideal for prolonged battery-operated motion
detection. Continuous motion sensing, signal processing and
event/motion detection is handled onboard by the Low-Power
DigiPyro, while the hosting microcontroller can be set into a power
saving mode. Only upon detection of motion, per its programmed
settings, the Low-Power DigiPyro signalizes the microcontroller to
wake up.
With this enhanced expansion of the DigiPyro Series, we now offer
a complete family of products in addition to PYD1688, PYD1698,
PYQ1648, and now PYD1588, PYD1598 and PYQ1548.
