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.
