The DP-005 digital
direction sensing pyroelectric infrared motion detector is designed to detect
infrared radiation (IR) from a moving human or animal both in daylight and at
night and to indicate the direction of movement.
Some applications are:
Entry and Exit
Child or animal
The circuits are housed in a
plastic enclosure with a Fresnel lens mounted in its cover. It includes dual
digital pyroelectric infrared sensors, a microprocessor and two output
transistors; one for each direction. An on-board voltage regulator powers the
circuits and accepts an external 4.5 to 15 volt DC power supply voltage.
The output transistors within
the DP-005 can sink up to 200 milliamperes each to directly drive relays, light
emitting diodes or other loads. The outputs can also be fed into a logic or
timing circuit to add specific functions such as robot control and counting.

Unlike typical analog pyroelectric sensors, the
digital sensor outputs serial data pulses that represent the amplitude of detected
infrared radiation in digital form. Since all of the amplification and
signal processing is done within the sensor package, the detector has very high
immunity to RF radiation from cell phones and other sources.
Driving light emitting
A resistor is required in
series with the LEDs to limit current. The resistor value can be chosen for the
power supply voltage and the desired LED intensity. Only one LED will be on at a
