I. Working principle

Vibration causes changes in capacitance and generates tiny voltages corresponding to changes. This voltage is then converted into a voltage of 0-5V accepted by the digital-to-analog converter of the collector. It is accepted by the data collector through A/D conversion and transmitted to the computer.

II. Specifications

Measuring range: 55 -110 dB(A);

Resolution: 0.1 dB(A)

III.Structure and function

1. The sensor terminal comes with a 1.8-inch color LCD screen.
2. The sensor terminal is equipped with 5 function buttons.The operation interface is simple and convenient.
3. The sensor terminal supports high-speed USB data channel, which enables high speed transmission of the data from the terminal to other devices such as PC, tablet or mobile phone.
4. The sensor terminal supportswireless communication with experimental terminals.
5. The sensor terminal has a built-in removable batterywith a capacityof 1800mAh.
6. The sensor terminal is designed with a hidden buckle sensor interface to support combined experiments with other sensors.
7. The sensor terminal has designed a fixation spot to get itfixed on the iron frameconveniently and combined with traditional lab equipment for experiments.
8. The sensor terminal supports the latest operating systems,such as iOS, Android, windows operating systems, etc.

IV.Typical applications

The wireless sound sensor functions as a microphone (microphone). It is used to receive sound waves and display the vibration image of the sound. It is suitable for vibration images of sound waves, sound wave interference, sound research, etc.

V.Caution

This product is suitable for educational use only and is not suitable for industrial, medical, research, or commercial applications.

VI.Usage Tips

1. The sound intensity sensor is used to measure the intensity of sound and should be aimed at the sound source when used.
2. In order to ensure the authenticity and continuity of acoustic data collection, please try to eliminate interference from noise and other factors.
