中国海域潮汐预报软件Chinatide的应用(China Sea tide forecasts Chinatide application software)

NTC热敏电阻计算器（B值、R25、指定温度、指定阻值均可计算，给定四个参数即可计算第五个参数）(NTC thermistors Calculator (B value, R25, specified temperature, the resistance can be specified calculation, four parameters can be calculated given the fifth parameter))

该项目首先是利用单片机对鱼缸的温度进行智能控制。首先通过外部按键对鱼缸所需温度进行设定。温度传感器 DS18B20 采集温度信息在外围的 LCD 上显示出来。其次是利用光电耦合器判断有无鱼饵，若无鱼饵，发出提示，若有鱼饵，则执行自动投食或手动投食功能。(The project first is the use of single-chip microcomputer to control the temperature of the fish tank. First, the temperature of the fish tank is set by the external button. The temperature sensor DS18B20 collects the temperature information to display on the periphery LCD. Followed by using photoelectric coupler to determine whether the bait, if there is no bait, alert, if there is a bait, automatic throw in and throw food or manually cast and functional food.)
