Humidity sensing characteristics of quartz crystal microbalance(QCM)humidity sensor coated with LiCl
whose mass ratio is 0.2 %
is studied.The experimental results show that the QCM humidity sensing unit with mass ratio 0.2 % LiCl humidity sensitive coating exhibits broad linear range of 13 %
9
4 %RH
high sensitivity
good repeatability
small hysteresis
digital output and nanogram-level measurement precision
