[0002]

2. Description of the Related Art A heat ray detecting automatic switch device detects a heat ray radiated from a human body by a heat ray sensor using a pyroelectric element, and turns on and off a load of a lighting fixture or the like. By automatically turning off the light, there is a feature that troublesome operation can be omitted and unnecessary power consumption such as forgetting to turn off can be prevented.

[0003]

However, since the conventional heat ray sensing automatic switch device has a single heat ray sensor integrated therein, the detection area is limited and the detection area of one heat ray sensing automatic switching device is limited. When setting a wide detection area that cannot be covered by the above, it is necessary to use a plurality of heat ray sensing automatic switch devices. On the other hand, a power supply line from a power supply and a load control line to a load are connected to each of the heat ray sensing automatic switch devices, and at least four terminals are required. Is very complicated.

In addition, if the load is a lighting fixture, there is a case where it is desired to turn on or turn off the light continuously regardless of whether a person enters or exits the detection area. It is considered to set a mode such as continuous lighting, continuous lighting, and the like. However,
In order to switch modes, an operation unit for mode switching must be provided at a position accessible to the user. In the case of the above configuration, the mounting location of the automatic switch for detecting heat rays is limited to a wall surface or the like. This makes it impossible to set the detection area near the center of a large room. When a plurality of heat ray sensing automatic switch devices are used, it is required that all the heat ray detection automatic switch devices in the room are set to the same mode. In the above configuration, the mode switching of each heat ray detection automatic switch device is individually performed. Must be done in
When there are a plurality of heat ray sensing automatic switch devices, mode switching is troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hot-wire sensor for detecting a heat ray from a human body and a controller for controlling the load on / off when a human is detected by the hot-wire sensor. An object of the present invention is to provide a heat ray sensing automatic switch device that can set a detection area of a heat ray sensor at an arbitrary position as a body.
