Macromolecule Humidity Sensor MS-Z3
Summary:
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 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.
Feature:
* Wide humidity detected rang
* Fast response
* Small Humidity hysteresis error
* Simple manufacture
* Easy integration
APPLICATION
Urban underground pipe gallery is a municipal public facility that implements unified planning, design, construction and maintenance, and is built in the city underground for laying municipal public pipelines.During the construction of the urban underground comprehensive pipe gallery, the workers are actually working in a closed environment or a closed space.
Compared with traditional agriculture, greenhouse planting is an intensive industry. In the current greenhouse projects, the main economic crops are vegetables, flowers, medicinal materials, etc. For agricultural planting, greenhouses can provide a relatively stable and controllable planting environment to improve the stable yield and quality assurance of crops. At the same time, greenhouse planting can also achieve mechanized control and reduce labor costs.
