Description of product


The Zio Qwiic Loudness Sensor is an I2C device making it easy to measure the noise level in your next project. No soldering required. The Loudness sensor can output ADC value (0-1023) to tell you the level of the noise. Also you can use this ADC value in other projects, like a sound sensor. The loudness value strongly depends on the distance between the sound source and the sensor.
