代码说明:

设计一种计算机教室温度、湿度检测系统,用于控制机房的温、湿度。整个系统采用STC89C51微处理器作为主控系统,硬件电路主要包括51单片机、DHT11温湿度传感器、显示器模块、警报器以及控制设备等5部分。通过给定的温湿度的上下限值并由1602 LCD显示器显示,传感器测量的信号由LCD显示出来,LCD显示实时的温、湿度值。当温、湿度超过限定值时,蜂鸣器鸣叫报警。

  • 猎鹰35B8.02双策略EA
    猎鹰35货币EA同时可交易35个货币对,简称猎鹰35B,这款EA可以满足不同类型交易者的需求,同时也是真正的低风险,高收益EA(月盈利率30%左右)。 策略原理:采用了低买高卖、高空低多和顺势开单两个策略。高空低多是在在动态中深度计算识别价格高低点,并且在单边行情只做趋势方向,振荡行情多空皆做;顺势策略是在回调时顺势开单,两个策略可同时开启也可单独使用(推荐使用双策略)。(Falcon 35 EA can trade 35 pairs of currencies at the same time, referred to as Falcon 35B, this EA can meet the needs of different types of traders, but also a real low-risk, high-yield EA (about 30% monthly profit). Strategic Principle: Two strategies are adopted: low-buy, high-sell, high-altitude, low-many and homeopathic billing. High-altitude and low-altitude are mostly used to identify high and low price points by deep calculation in dynamic state, and only do trend direction in one-sided market, while oscillating market is done in many empty places. Homeopathic strategy is to open orders in the callback, and both strategies can be opened at the same time or used separately (double strategy is recommended).)
