The iTriangle - Sound sensor can detect the sound intensity of the environment. The main component of the module is a simple microphone, which is based on an LM386 amplifier and an electret microphone. This module's output is analogue and can be easily sampled and tested with iTriangle.
- Easy to use
- Provides an analogue output signal
- Easily integrates with logic modules on the input side of iTriangle circuits
This sound sensor is used only to detect the presence of sound in the nearby environment. Please do not use the module to collect sound signals. For example, you can use it to make a sound activated lamp, but not as a recording device.
