The working principle of noise noise sensor detection module
The noise sensor is precisely because the sensor has a built-in condenser electret microphone that is sensitive to sound. The sound wave makes the electret film in the microphone vibrate, resulting in the change of capacitance and the corresponding change of tiny voltage, so as to realize the optical signal to the conversion of electrical signals.
Noise noise sensor detection module features
1. The direct-reading noise decibel detection module developed by the original imported sound sensor;
2. Multi-point calibration process production, high detection accuracy and high sensitivity;
3. The unique stainless steel probe is independently packaged and designed to be easily embedded in other equipment or casings;
4. The core components of the main control board circuit are completely shielded, which is not only beautiful but also enhances the anti-interference ability;
5. Reserve a variety of output TTL/I2C, standard Modbus Rtu communication 485 interface optional, suitable for various application integration.
