Beschreibung
Zusammenfassung:	The utility model discloses an LED dimming energy-saving sensor including an infrared sensor probe, a first signal amplifying circuit, a second signal amplifying circuit, a CDS circuit, a CPU control circuit, a PWM adjusting circuit and a power source unit. The power source unit is connected with the infrared sensor probe, the CDS circuit and the PWM adjusting circuit respectively. The infrared sensor probe receives pyroelectric infrared rays having wavelengths of 7 to 10 micrometers. The pyroelectric infrared rays are amplified by the first amplified circuit and are sent to the second amplifying circuit after the amplification for further amplification. Signals are sent to the CPU controller for operation. A PWM pulse modulation wave is output after the operation to control the PWM dimming circuit, thereby adjusting the luminance of an LED lamp. The CDS circuit is a sensor controlling the work of a whole circuit. The LED lamp is turned off in the daytime having high light intensity while the LED lamp starts
