The motion sensor detects human motion by receiving infrared rays and sends the pulse wave
output.
The microcomputer in the indoor unit carries out a sampling every 20 msec. If the motion sensor
detects 10 times or more of the wave output in one second in total, and the High signal
continues for 3 sec., the microcomputer judges humans are in the room as the human detection
signal is ON.
