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.

Technical information regarding the devices is available in the data sheets on the products page of this web site.
