The E931.62 integrated circuit is designed for interfacing Passive Infrared (PIR) sensors with micro-controllers or processors. A single wire Data Out, Clock In (DOCI™) interface is provided for interfacing with a micro-controller. Multiple devices can easily be operated at the same time.
Up to two PIR sensors elements connect directly to the PIR inputs. The PIR signal is converted to a 14 bit digital value. The E931.62 contains an on chip temperature measurement circuit with a resolution of better than 0.1K. The PIR sensor voltages and the temperature value are supplied to an external microcontroller through the DOCI™ interface.
