Papers by Keyword: AT89S51 Single Chip Microcomputer

Abstract: This phototherapy takes full advantage of near infrared ray with high penetrability treating various pains and UVC curing gynaopathy, yet using the same control system. Introducing emphatically AT89S51 as the core to control circuit, utilizing PWM (Pulse-Width Modulation) produced by singlechip to manage the transmit power of light source and implementing the control system into hospital’s RS-485 monitoring network. Because of the machine serving several purposes, it makes the treatment efficiency higher and the cost lower.
