Macromolecule Humidity Sensor MS-Z2

Summary:

MS-Z2 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 and the activated energy of macromolecule polyelectrolyte
counter-ions will decrease, drift mobility will increase and impedance will decrease. And
then when humidity decreases, water molecules are released from ion polymer and the
resistor of material will increase. The environment humidity can be monitored through
testing the impedance.

Application
Humidity sensor, as an important chemical sensor, which is widely used in fields of
warehousing, industry production, and process control, environmental monitoring, home
appliances and meteorology etc.

Feature:

* Wide humidity detected rang
* Fast response
* Small Humidity hysteresis error
* Simple manufacture
* Easy integration
