High-Sensitivity Acoustic Sensor for Noise Detection

A noise sensor is a device used for detecting and monitoring noise. It realizes the monitoring and control of noise by converting the vibration of sound waves into electrical signals. The core component of the noise sensor is a highly sensitive electret condenser microphone.
Integrated Environment Temperature Humidity Pressure Noise Sound Voice Level Detection Sensor Noise Measuring Instrument

The noise sensor is equipped with a capacitive electret microphone that is sensitive to sound. When sound waves cause the electret film to vibrate, it will lead to a change in capacitance, thereby generating a corresponding tiny voltage. This voltage variation realizes the conversion from sound signals to electrical signals.
