How to use Triple Channel DigiPyro
Basics – Application - Advantages
Introduction
The Triple Channel, PYQ 2898, is the
newest addition to the growing DigiPyro
family of digital pyroelectric infrared
detectors, brought to you by PerkinElmer.
The Triple Channel Quad Element
detector is the high end version of the
DigiPyro
elements representing two channels and
an additional temperature reference
channel. It is a quad element
configuration which is connected to a
special integrated circuit. It contains the
analog-to-digital converter, a temperature
sensor, the low-power oscillator and a
serial interface, all in a standard three-pin
TO-5 housing. It offers a 42 bit ” direct
link” interface.
The move from analog to digital
technology enables the DigiPyro
deliver a number of advantages including
space savings from fewer components
and significantly improved EMI immunity.
With the addition of the PYQ 2898 to the
DigiPyro
another step-change in digital motion
detection, for the first time enabling low-
cost, quad element systems.
