摘要：本水位監(jiān)測報(bào)警器使用5V低壓直流電源（也可以用3節(jié)5號(hào)電池代替）就可以對(duì)5~15厘米的水位進(jìn)行監(jiān)測，用LED顯示和數(shù)碼管顯示水位，并可以對(duì)不再此范圍內(nèi)的水位發(fā)出報(bào)警。主要采用CD4066、74LS86、74LS32、CD4511芯片，再加上數(shù)碼管、蜂鳴器、發(fā)光二極管、電阻這些器件組成一個(gè)簡單而靈敏的監(jiān)測報(bào)警電路，操作簡單，接通電源即可工作。因?yàn)榇蟛糠蛛娐凡捎脭?shù)字電路，所以本水位監(jiān)測報(bào)警器還具有耗能低、準(zhǔn)確性高的特點(diǎn)。關(guān)鍵字：譯碼電路 報(bào)警電路 監(jiān)測電路 Abstract: The water level alarm monitoring the use of 5 V low-voltage DC power (can also use three batteries replaced on the 5th) will be able to 5 to 15 centimeters of water level monitoring, with LED display and digital display of water level, and this can no longer Within the scope of a water level alarm. Mainly CD4066, 74LS86, 74LS32, CD4511 chips, coupled with digital control, buzzer, light-emitting diode, the resistance of these devices composed of a simple and sensitive monitoring alarm circuits. Because the majority of circuits using digital circuitry, so the water level monitored alarm system also has low energy consumption, high accuracy of the characteristics.
