An ultra-low-power high-precision automatic dust monitor was designed and implemented to accurately detect dust on the air conditioning heat sink. The system is composed of ARM processor,photoelectric sensor array module,weak sig-nal processing circuit,analog-digital conversion circuits,LCD touch screen display and input module,sound and light alarm system,relay switch control circuit,clock module and serial communication module. Taking STM32 microprocessor as a master controller,the differential detection for dust on the air conditioning heat sink is executed by the pulse-driving photoelectric sen-sor array. The low-noise AD7195 ADC excited by AD is used to convert the amplified and filtered voltage signals into digital sig-nals. The microprocessor is employed to analyze and process the received digital signals,which can generate the monitoring re-sults displayed by LCD and the sound-light alarm,forcibly close air conditioning,and remind the user promptly that they have to clean the air conditioning heat sink. The practical application shows that the intelligent automatic dust monitor for air condi-tioning heat sink can effectively and precisely achieve real-time display,optoelectronic alarm,PC communications and other functions. It can be used to monitor various types of air conditioning heat sink,and has a strong practical value.
