The BYZ08-ZY noise detection sensor module adopts imported components to calibrate the output signal TTL and IIC, designed for low-cost application users of integrators. The direct reading noise detection module is uniformly calibrated in the experimental cabin, and the data is stable and reliable.

This product is widely used in scientific research institutions, 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 that require measurement.

The noise sensor is precisely because the sensor is equipped with a sound sensitive capacitive polarizer microphone. Sound waves cause the polarizer film inside the microphone to vibrate, resulting in a change in capacitance and a corresponding small voltage change, thus achieving the conversion of optical signals to electrical signals.

1. A direct reading noise decibel detection module developed using original imported sound sensors;

2. Multi point calibration process production, high detection accuracy, and sensitivity;

3. Unique stainless steel probe independent packaging design, easy to embed into other devices or casings;

4. The core components of the main control board circuit are completely shielded, which not only looks beautiful but also has strong anti-interference ability;

5. Multiple output TTL/I2C and standard Modbus Rtu communication 485 interfaces are reserved for integration in various applications.

5、 Noise standards

Noise level	Environmental standards (based on the hearing of ordinary people)
0～20 dB	Very quiet, almost imperceptible;
20～40 dB	Quiet, like soft whispers;
40～60 dB	General and ordinary indoor conversations;
60～70dB	Noisy and nerve damaging;
70～90dB	It's very noisy and nerve cells are damaged.
90～100dB	Increased noise and hearing loss;
100～120dB	Unable to tolerate, temporarily deaf after just one minute.
Above 120dB	Extremely deaf or completely deaf
