SND1000 User Guide
Welcome to the SND1000 user guide! In order to get started, make sure you have the following hardware on hand:
Next, you will need to connect the pieces:
- Connect the SND1000 to your VINT Hub using the Phidget cable.
- Connect the VINT Hub to your computer using the USB cable.
Now that you have everything together, let's start using the SND1000!
Using the SND1000
Phidget Control Panel
In order to demonstrate the functionality of the SND1000, the Phidget Control Panel running on a Windows machine will be used.
The Phidget Control Panel is available for use on both macOS and Windows machines.
To open the Phidget Control Panel on Windows, find the icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel
To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the icon to bring up the Phidget Control Panel.
For more information, take a look at the getting started guide for your operating system:
Linux users can follow the getting started with Linux guide and continue reading here for more information about the SND1000.
After plugging the SND1000 into your computer and opening the Phidget Control Panel, you will see something like this:
The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:
- Serial number: allows you to differentiate between similar Phidgets.
- Channel: allows you to differentiate between similar objects on a Phidget.
- Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
Double-click on the Sound Sensor object, labelled Sound Phidget, in order to run the example:
General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:
- Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
- Use the SPL Range drop-down menu to select the lowest possible range that the level of sound you're measuring will fall within (smaller ranges have higher resolution).
- Use the Speaker Beep tool to emit a 2.5 second beep of the specified frequency. View the frequency bands and see how they respond.
Finding The Addressing Information
Before you can access the device in your own code, and from our examples, you'll need to take note of the addressing parameters for your Phidget. These will indicate how the Phidget is physically connected to your application. For simplicity, these parameters can be found by clicking the button at the top of the Control Panel example for that Phidget.
In the Addressing Information window, the section above the line displays information you will need to connect to your Phidget from any application. In particular, note the Channel Class field as this will be the API you will need to use with your Phidget, and the type of example you should use to get started with it. The section below the line provides information about the network the Phidget is connected on if it is attached remotely. Keep track of these parameters moving forward, as you will need them once you start running our examples or your own code.
Using Your Own Program
You are now ready to start writing your own code for the device. The best way to do that is to start from our Phidget is compatible with the [https://www.phidgets.com/?view=code_samples&class=SoundSensor SoundSensor Examples. Code Samples].
Select your programming language of choice from the drop-down list to get an example for your device. You can use the options provided to further customize the example to best suit your needs.
Once you have your example, you will need to follow the instructions on the page for your programming language to get it running. To find these instructions, select your programming language from the Programming Languages page.
Depending on your application, you may be interested in acoustic data with weightings applied. The SND1000 returns a SPL value with the A-weighting applied, C-weighting applied, and with no acoustic weighting applied.
The microphone on the SND1000 is slightly more responsive to some frequencies than others. The following graph illustrates this difference:
