PIR Motion sensors (Passive Infrared or Pyroelectric)
from Panasonic for optimal
usability and reliability
Panasonic develops and produces PIR Motion sensors, which combine easy integration,
high reliability and environment-friendly materials.
The Panasonic PIR Motion sensors abbreviated as PaPIRs, has three series of products, including

Better sensitivity
（

The sensitivity has been significantly improved thanks to a unique slit
design of the pyroelectric elements. The separated sensing areas prevent
thermal crosstalk between the single sensing elements. Therefore, reliable
detection is possible even if the temperature difference between the

Better signal-to-noise ratio
（

）
Improved signal-to-noise ratio thanks to a special I/V circuit which is used
for converting a current signal from the pyroelectric element to voltage.
Panasonic PIR Motion sensors perform by the feedback capacitor and the
operational amplifier, different from the conventional FET-type, thereby
decreasing the probability of false alarms due to temperature fluctuation.
