基于高灵敏恒温控制器的设计与应用

摘要

为了实现动、植物的恒温养殖，设计了一种高灵敏恒温控制器，它是由热敏电阻作为传感元件，由极性相反的两个三极管组成高灵敏度开关电路，由光电三极管直接控制可控硅的接通与断开，由此而形成了高灵敏恒温控制。该电路经过多年的使用，效果显著，值得推广。%In order to achieve the constant temperature breeding of animals and plants, we designed a kind of high sensitive constant temperature controller. It take the thermistor as sensing element, two opposite pole triode formed high sensitive switch circuit, photoelectric triode controll the connection and disconnection of silicon controlled rectifier directly. Through these measures, high sensitive temperature control was realized. After years of use,the circuit is effective and worth promoting.
