Sensors that use acoustic waves in the medium.
Audio detector powered with the voltage ranging from 3.5 to 5.5 V. The module is easy to use, it has three outputs: an analog - to measure the intensity of the signal, digital - is changing the status when exceeding a certain level and the audio output.
Module with silicon microphone, MEMS type, which does not require amplifier. It detects sound with frequency from 100 Hz to 10 kHz and converts it into an analog output signal that can be read using the A/D converter. The device operates with a voltage from 3.3 V to 5 V.
Module from the Grove series, based on the system LM2904 and a microphone. It can be powered with a voltage ranging from 3.5 V to 10 V. The output is the analog signal. The sensor can detect the strength of the environment's sound. It has an analog output that makes it compatible with most of the commissioning modules, including Raspberry Pi and Arduino.
Sound module with built-in decoder VS1003B. It has line input and line output for connecting a microphone and headphones. The board has also a simple microphone. The module communicates using the SPI bus, it is powered with the voltage of 3.3 V.
The sound level meter is compatible with Arduino. For measurements, it uses the circuit instrument and the microphone with a low noise level that allows to accurately measure the sound level in the environment. It measures the sound in the range of 30 DBA to 130 DBA. It is powered with the voltage from 3.3 V to 5 V.
Module from the Grove series, based on the LM386 system and electret microphone. It can be powered with any voltage from 4 V to 12 V. The output is an analog signal. The sensor can detect the sound strength in the environment. It has an analog output what makes it compatible with most commissioning modules, including Raspberry Pi and Arduino.
Vibration sensor with flexible plastic piezoelectric sensor LDT0-028. It is supplied with 5V, works with modules from Arduino, Raspberry Pi and other microcomputers/controllers. Flexible sensor leads to the generation voltage. Range (0.001 Hz to 1000 MHz) can be adjusted using the built-in potentiometer. The kit also includes a cable Grove.
Audio detector powered with the voltage ranging from 3.3 V to 5 V. The module is easy to use, it has two outputs: analog - to measure the intensity of the signal and digital - changing the status when exceeding a certain level.
Sound sensor that detects the sound of music, applause, pstrykania, etc. Can identify 500 digital sounds. Initially the sensor was used in Heelight, intelligent light bulb controlled by sound. Sensor with Grove interface can be controlled using Arduino.
