资 源 简 介

摘要:本水位监测报警器使用5V低压直流电源(也可以用3节5号电池代替)就可以对5~15厘米的水位进行监测,用LED显示和数码管显示水位,并可以对不再此范围内的水位发出报警。主要采用CD4066、74LS86、74LS32、CD4511芯片,再加上数码管、蜂鸣器、发光二极管、电阻这些器件组成一个简单而灵敏的监测报警电路,操作简单,接通电源即可工作。因为大部分电路采用数字电路,所以本水位监测报警器还具有耗能低、准确性高的特点。

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.
