Product details

LM2904 Sound Intensity Detection Module Analog Decibel Detection Noise Control Sensor Microphone Module

Due to excessive ambient noise in the detection environment, the displayed sound intensity curve exhibits significant fluctuations; however, the continuity of the sound signal waveform remains clearly visible. Product Application Scopes: Suitable for detecting environmental parameters such as: sound volume, presence/absence of sound, whistling, and sound intensity. *Note: This product cannot identify specific sound frequencies and is therefore unsuitable for applications requiring the detection of particular frequency bands. Usage Recommendations: 1. To ensure the quality of the output signal, please use a stable power supply with minimal ripple whenever possible. 2. To achieve a higher output signal amplitude, the module's supply voltage may be increased; however, this voltage must not exceed the module's specified allowable operating range. 3. When using an ADC chip for data acquisition, it is recommended to connect an external pull-down resistor (ranging from 1kΩ to 10kΩ) between the output pin and ground. The specific resistance value should be selected by the user based on the requirements of their particular application scenario. Color: Blue Material: plastic Package Contents: 1*Sound Intensity Detection Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
