目前我国部分农村的自来水采用人工合闸定时供水方式,这样既节电又节水。本文介绍的电路,可以完成自动供水的控制任务,它可以每隔2h(小时)给水2h(小时),免去了人工操作的繁锁。电路如图1所示。图中的IC1为数字集成电路 At present, tap water in some rural areas of China adopts artificial closing timed water supply, which saves energy and saves water. This article describes the circuit to complete the automatic water supply control tasks, it can be every 2h (hours) for 2h (hours), eliminating the need for manual operation of the cumbersome. Circuit shown in Figure 1. The figure IC1 for digital integrated circuits
