StreetNoiseSensor

Arduino library for background RMS measurement of street noise using a microphone (e.g. Max9814) on SAMD21 (Arduino Zero).

Features

• No large buffer required.
• Timer interrupt on TC4 for continuous ADC sampling.
• On-the-fly RMS calculation from startMeasurement() until stopMeasurement().

Installation

1. Place the StreetNoiseSensor folder into your Arduino libraries folder.
2. Restart the Arduino IDE.

Usage

See the example StreetNoiseTest.ino.
