1. A transceiver system comprising:
- a transmitter device monitoring a state of a monitored object and transmitting a monitoring result;
the transmitter device comprisinga sensor unit including a state detection sensor detecting the state of the monitored object, and a motion sensor detecting a physical operation of the monitored object,a transmitter signal processor section causing the state detection sensor to operate according to an output of the motion sensor, anda transmitter section transmitting a detection result of the state detection sensor; and
a receiver device receiving data from the transmitter device,whereinthe sensor unit operates intermittently by repeating an operation period and a stop period,the motion sensor detects the physical operation of the monitored object in the operation period, andthe transmitter signal processor section changes an operation timing when the sensor unit operates next time according to past and/or present physical operation of the monitored object.

Abstract
A transmitter module has a sensor module that includes a plurality of sensors and operates intermittently, a signal processor module that permits transmission of an output of the sensor module to a receiver module at given permission timings, a radio transmission module that wirelessly transmits data when the transmission is permitted, and a power source that supplies power to each module. The signal processor module has a microcomputer and an interval timer that outputs a first timing signal when a count value corresponds to a set value. The microcomputer is activated by the first timing signal and changes the set value in a compare register according to a vehicle operation state.
