Abstract
Provided are a sensor unit and function activation method that make it possible to collectively activate the functions of a plurality of sensor units. A sensor unit 10, which can be connected to other sensor units 10 to form a unit series, comprises an activation unit 64 for activating a prescribed function on the basis of a signal from the outside and a signal output unit 65 for outputting a trigger signal for activating a prescribed function to the outside on the basis of a signal from the outside.
Claims14
A sensor unit, capable of forming a unit series by connecting a plurality of sensor units, the sensor unit comprising:
- an activation unit, activating a prescribed function based on a signal from outside;
- a signal output unit, outputting a trigger signal for activating the prescribed function to the outside based on the signal from the outside;
- and
- a light communication unit capable of light signal transmission and reception,
- wherein the signal output unit transmits a light signal comprising the trigger signal to one of the sensor units in the unit series by using the light communication unit.
A function activation method for a sensor unit capable of fonning a unit series by connecting a plurality of sensor units, the function activation method comprising:
- an activation step of activating a prescribed function based on a signal from outside;
- and
- a signal output step of outputting a trigger signal for activating the prescribed function to the outside based on the signal from the outside,
- wherein the signal output step comprises transmitting a light signal comprising the trigger signal to one of the sensor units in the unit series.
