Products Description
The noise sensor module uses imported components to calibrate the output signal TTL and RS485. It is designed for integrators and low-cost application users. It is a direct-reading noise detection module with unified calibration in the experimental cabin, and the data is stable and reliable.
This product is widely used in scientific research units, portable/handheld detectors, fixed gas transmitters, atmospheric environment detectors, dust and noise detection systems, noise monitors, detectors, automation control systems, environmental noise monitoring systems, industries, factories and other places where measurement is required.
The noise sensor has a built-in sound-sensitive capacitive electret microphone. The sound waves make the electret film inside the microphone vibrate, causing the capacitance to change, and generating a small voltage that changes accordingly, thereby realizing the conversion of optical signals into electrical signals.
