    You could use 2 MCUs.

    One (MCU_1) could be the sensor controller and would monitor all the sensors, do any conversion or scaling required and store their current value or status.

    The other (MCU_2) could be the alarm controller and would be responsible for alarm triggers, arming and communications.

    MCU_2 could query MCU_1 on a regular basis to get the current sensor status and respond accordingly. Communication between them could be done through one of the popular serial protocols.

    Roman Black has a pretty good way of doing this.

    You can get the cheapest little 10F pic, attached to the sensor..as many as you want.

    It only requires 1 wire communications. The PIC and sensor can be battery operated, and connect to a MASTER station.

    Here is a link to the details:
