ABNORMALITY SENSOR AND SENSOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an abnormality sensor using an infrared ray remote control while reducing the power consumption.SOLUTION: The abnormality sensor includes a light receiving section which has a function to communicate with an operation terminal 20 which responds to an infrared ray remote control 30 which is different from an operation terminal 20. When receiving a predetermined command signal from an operation terminal 20, the light receiving section is set to an operation state to perform a series of processing corresponding to the operation signal issued by the infrared ray remote control 30.SELECTED DRAWING: Figure 3
