摘要
An impedance type humidity sensor based on the polyacrylic emulsion containing magnesium chloride (MgCl2) without chemical modification was investigated. The impedances of the sensor were measured from various relative humidity in the frequency range between 0.1 kHz and 100 kHz. The sensor has a good sensitivity from 60% RH to 90% RH. According to the experimental results, the response time is about 240 seconds in the adsorption process and 310 seconds in the desorption process.
