New product M2012A PIR Signal Processor

The M2012A PIR signal processor interfaces between a standard Passive Infra-red Sensor (PIR) and a micro controller. The M2012A performs ADC conversion and digital low pass filtering of the PIR signal. The digital PIR signal is supplied via a single pin serial interface to the micro controller. The micro controller is free to do more sophisticated signal processing with the filtered data received from the M2012A.
