Design for Heater Control System Based on DS18B20 and Level Detector

This paper describes a control system design forwater heater devices. We use DS18B20 and water sensor tocollect the data of water temperature and water level, displaythe data via LED, and compare the data with the preset value,use STC89C51 to control relays, thus we can control the heaterand water pump's turn on or turn off. This system also has thealarm device for temperature and level's overtop or overlow.
