Zhengzhou Winsen Electronics Technology Co., Ltd MS-Z3 Macromolecule Humidity Sensor Overview MS-Z3 humidity sensor is made of high polymer humidity sensitive material. In wet conditions, water molecules are adsorbed by polar group on the surface of martial. And as the humidity increases, the quantity of water molecules will be changed accordingly. The adsorbed water is gradually condensing and coming into be liquid, which is electrolyte solution with current channel quality. With the humidity increasing, macromolecule will swell, interior free volume will be bigger, carrier will be increased...

Zhengzhou Winsen Electronics Technology Co., Ltd Sensor Structure Application Circuit Working principle: Use IO port of single-chip microcomputer to have an output of a square wave of 1KHz. Charge capacitor through R1 (humidity resistor MS-Z3). Note down charging time when IO port’s low level reverts to high level, and then get humidity value by calculation. Note: the ratio of the high level should be higher than that of low level, otherwise it cannot be fully charged. MS-Z3 Detection Electric Level Charge Capacitor Note ⚫ In order to prevent polarization, the voltage or current used to drive...
