1、淋浴水溫調(diào)節(jié)器設(shè)計(jì)摘要目前淋浴熱水器在家庭中運(yùn)用越來越廣泛，然而市面上存在的淋浴調(diào)節(jié)方式主要是通過手動(dòng)調(diào)節(jié)開關(guān)量的大小來控制水溫的高低。這種調(diào)節(jié)方式不能夠很好的控制水溫的高低，有時(shí)由于調(diào)節(jié)開關(guān)距淋浴地點(diǎn)較遠(yuǎn)，給人們調(diào)節(jié)水溫帶來不便，因此，這種調(diào)節(jié)方式不能夠滿足人們追求生活舒適的要求。本論文介紹了一種以單片機(jī)為主要控制器件，以DS18B20為溫度傳感器的新型淋浴水溫調(diào)節(jié)器。它主要包括硬件電路的設(shè)計(jì)和軟件設(shè)計(jì)。硬件電路主要包括主控制器，測溫控制電路和顯示電路等，主控制器采用單片機(jī)STC89C54RD+，溫度傳感器采用DS18B20，顯示電路采用8位共陰
