电化学气体传感器工作电路的设计

Design of Electrochemistry Gas Sensor Circuit

本文论述了电化学气体传感器工作电路设计中应注意的问题，并设计出低电压下工作的低功耗工作电路和低电压工作的数字电压表。

The author describes some problems that should be paid attention to in the design of electro chemistry gas sensor circuit. The low power and low voltage digital voltmeter which work under the low voltage condition are designed. So they can make up the digital hand device of measuring gas density.
