Product description: Iduino ST1146 - sound sensor - microphone
The sound detector with a small electret microphone, a voltage supply range from 3.3 V to 5 V. The module is easy to use, hastwo outputs: an analog- to measure the intensity of the digital signal and changing state when exceeding a certain level.
Using sound sensor Iduino
The sensor has a 4-pin connector with analog and digital output A0 D0 to be attached to the pin of the microcontroller, e.g.an Arduino.
| Pin | Description |
|---|---|
| A0 | The output of the analog signal. |
| g | The ground of the system. |
| + | Supply voltage range from 3.3 V to 5 V. |
| D0 | The output digital signal. |
