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.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

I'm not the only one, either. Locks up the I2C bus and the MCU its connected to can't read a value after just a few seconds.
This is the first time I decided to try out several Qwiic modules and have been actually surprised at how fast everything was running. Especially in combination with other Qwiic or Zio modules, the loudness sensor worked perfectly fine. And with the sample code provided, I could measure the loudness and display it on the other Zio Qwiic display in just a few minutes. Even the sensitivity and response time was better than expected. Good job here!
This was super helpful for measuring noise and easy to pair with the Zio Qwiic display! I found that it was quite sensitive, which was helpful when I tried to make a noise-activated feedback system for my speakers. I would recommend this if you are looking for something cheap but good quality.
