Abstract
AT89C52 microcontroller system using cooling towers to achieve the level of automation, design a low cost and high practical value of the water tower water level controller. The s
ystem has the water level detection, low water high water level alarm and automatic functions such as adding water. The design process mainly uses the sensor technology, single chip technology, optical technology and the weak control the strong police power technology. Detection system using simple system for detection of copper needles, resulting in the low and high sensitivity. 52 SCM system control by using the circuit of signal processing and the use of optical coupling and weak control relays to achieve strong power to realize automatic control of water systems.
It can automatically detect the water level, light alarm, Sheung Shui, all the work without water cycle, to ensure better surface height is always within the context of its structure simple, low cost, high sensitivity, significant energy is used in various kind of ideal equipment for high-level liquid storage
