What is a comparator?
When does current consumption standby
occur?
The amount of infrared radiation emitted from the human body is very
small, and the signal cannot be processed by the circuit as is. For this rea-
son, the signal is amplified by the amplifier circuit. The amplified signal must
then be compared to the reference level. If the amplified circuit is greater
than the reference level, a person is considered to have entered the detec-
tion area and a signal is output. The circuit that makes this comparison
is called a comparator.
When the time required for stabilization has elapsed and the sensor is
ready for detection, two states are possible depending the condition of the
detection area:
Number 2 above is the standby state. (Number 1 is the detection state.)
The difference between the standby state and the detection state is that the
output circuit is off in the standby state, and therefore current consumption
is less than in the detection state.
1. A person has entered the detection area (detection output ON)
2. Nobody is in the detection area (detection output OFF)
