M2006C
PIR Motion Detector
General Description___________
The M2006C integrated circuit combines all required
functions for a single chip Passive Infra Red (PIR)
motion detector.
A relay and a LED output are provided for interfacing to
an occupancy detect or alarm system.
One or two PIR sensors connect directly to the PIR
inputs. The pull-down resistors and DC decoupling
circuitry are integrated on chip. The PIR signal is
converted to a 15 bit digital value.
The parameters for sensitivity, pulse count and timing
are set by means of connecting the corresponding
inputs to VDD, VSS or leaving them open.
The voltage level on the temperature compensation
input is converted to a digital value with 4 bit resolution.
All signal processing is performed digitally.
Applications_________________
♦ PIR motion detection
♦ Intruder detection
♦ Occupancy detection
♦ Motion sensor lights
Features_____________________
♦ Digital signal processing
♦ On chip supply regulator with wide operating voltage
range
♦ Low power consumption
♦ Temperature compensation input
♦ Differential PIR sensor input
♦ Selectable relay output polarity
♦ Selectable pulse count and timing algorithm for
motion detection
