Abstract: Aiming at the functional necessity and market requirement of a controller for small singlescrew air compressor, based on AVR technology, associated with modularized flexible design theory, a controller for small singlescrew air compressor was designed. The system recognizes ATmega16 microcontroller as its foremost part. The peripheral interface circuits of the system, including A/D sampling, switch input, keyboard scan, LCD display and alarm etc., were designed. Simultaneously, relative system software about the controller was exploited. Through actual engineering test and application, the result indicates that the controller is featuring lowcost and wellfunctioned, which perfectly meets the need of the market.
Key words: AVR microcontroller; screw air compressor; control system design
