The MS-Z302 is based on the polymer humidity-sensitive material principle. Its sensing element is made of a hydrophilic polymer film with conductive particles embedded inside.
In a high-humidity environment, the polymer film absorbs water vapor, causing the conductive particles to disperse and the sensor’s resistance to increase significantly.
In a low-humidity environment, the polymer film releases water vapor, making the conductive particles aggregate closely, and the sensor’s resistance decreases accordingly.
The resistance value of the sensor has a stable logarithmic relationship with relative humidity (RH). By measuring the resistance change and converting it through a signal conditioning circuit, accurate relative humidity values can be obtained.
2. Key Features:
High Measurement Precision: With a typical humidity measurement accuracy of ±2% RH (at 25°C, 20%–80% RH), it meets the requirements of high-precision humidity monitoring scenarios.
Wide Detection Range: Covers a relative humidity range of 0%–100% RH, supporting both dry and saturated humidity environment detection.
Fast Response & Recovery: T₉₀ response time ≤ 5 seconds (humidity rise) and T₉₀ recovery time ≤ 8 seconds (humidity drop), enabling real-time tracking of ambient humidity changes.
Compact & Easy Integration: Adopts a miniaturized probe design, with standard pin or solder pad interfaces, suitable for direct integration into humidity detectors, HVAC systems, and smart sensors.
Strong Environmental Adaptability: Works stably in a temperature range of -20°C to +60°C; resistant to dust and mild corrosive gases, suitable for indoor and outdoor use.
Low Power Consumption: Passive component design (no external power supply required for resistance output), minimizing power consumption of the host device.
3. Typical Applications:
Ambient humidity detectors and handheld environmental meters
HVAC (Heating, Ventilation, and Air Conditioning) system humidity control
