Description
The MS-Z202 type humidity sensor is made from high-molecular humidity-sensitive materials. When the environmental humidity rises, the high-molecular material experiences swelling. This swelling leads to an expansion of the internal free volume, increasing the number of carriers. Simultaneously, the activation energy of the counterions in the high-molecular polyelectrolyte decreases, enhancing their mobility, and causing the impedance of the material to decrease. On the contrary, when the environmental humidity decreases, water molecules escape from the ionic polymer, increasing the resistance of the material. By measuring these impedance changes, the relative humidity in the environment can be accurately monitored.
Application
As a vital chemical sensor, the MS-Z202 humidity sensor has extensive applications. In warehouse storage, it helps maintain the proper humidity level to safeguard stored items. In industrial production settings, it ensures product quality by controlling the humidity in the production environment. For process control purposes, it supplies real-time humidity data for precise process adjustments. In environmental monitoring, it plays a crucial role in assessing overall environmental conditions. In household appliances, it can be integrated to optimize device performance. Moreover, it's valuable in meteorological applications for accurate weather predictions.

Technical Support:
Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.
The sensors don't have sleeping mode. It can be set in program if needed.
All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.
The sensor has been fully tested (not calibrated) before leaving the factory, but the module will be calibrated before leaving the factory.
However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.
15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.
Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.
Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.
Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to sales@winsensor.com
