本文介绍的电路是一个气体泄漏探测器.它的核心是4093施密特四与非门CMOS集成电路。在本电路中只用到其中的两个门。电路可以及时有效地探测许多种可燃性气体(如丁烷气及异丁烷气等)是否泄漏,这样就可以有足够的时间来避免潜在事故的发生。一个专门设计的传感器是本电路的核心部件,它是一个白金线圈.表面涂覆了化学氧化催
This article describes the circuit is a gas leak detector. It is the core of the 4093 Schmidt NAND gate CMOS integrated circuits. Only two of these gates are used in this circuit. Circuit can be timely and effective detection of many kinds of flammable gases (such as butane gas and isobutane gas, etc.) for leakage, so that you can have enough time to avoid potential accidents. A specially designed sensor is the heart of this circuit, it is a platinum coil. The surface is coated with a chemical oxidation catalyst
