Wireless humidity sensor

I. Working Principle

The sensor is designed based on a humidity-sensitive element, which is essentially a variable capacitor whose capacitance changes with ambient humidity. The measured output is converted into a 0–1 V electrical signal and transmitted to the analog-to-digital converter of the data acquisition system.

II. Specifications

Range: 0–100 %; Resolution: 0.1 %

III. Structure and Features

1. Equipped with a 1.8-inch color LCD screen.
2. Configured with five functional buttons for simple and convenient operation.
3. Supports high-speed USB data transfer for rapid communication with data acquisition systems.
4. Enables wireless communication with experimental terminals.
5. Features a built-in large-capacity removable battery.
6. Includes a snap-fastened sensor interface for compatibility with standard sensors in combined experiments.
7. Provides fixed mounting points for attachment to iron stands for integration with traditional equipment.
8. Compatible with operating systems such as iOS, Android, and Windows.

IV. Typical Applications

The humidity sensor measures the relative humidity of air or gases. It is primarily suitable for humidity-related experiments, including environmental humidity measurement, studies on the relationship between temperature and humidity, and investigations into the effects of desiccants.
