Abstract
A human body detecting device includes a pyroelectric infrared radial (PIR) sensor, a thermometer, a processor, an amplifying unit, and a plurality of amplification adjusting units. The PIR sensor is configured to sense infrared radiation and then generate an electronic signal. The thermometer is configured to sense an ambient temperature and then generate a temperature value. The microprocessor is electrically connected to the thermometer, and the amplifying unit is electrically connected to the pyroelectric infrared radial sensor and the microprocessor. The amplification adjusting units corresponding to a plurality of temperature intervals are electrically connected to the microprocessor and the amplifying unit. The microprocessor selects to enable one of the amplification adjusting units based on a comparison between the temperature value and the temperature intervals, such that the amplifying unit may modulate the electrical signal according to the enabled amplification adjusting unit.
