This library lets you run machine learning models and collect sensor data on machines using Node.js. The SDK is open source and hosted on GitHub: .
See our to learn more about the .eim file format.
Add the library to your application via:
To setup the parameters of the Edge Impulse CLI, have a look at the helper:
Before you can classify data you'll first need to collect it. If you want to collect data from the camera or microphone on your system you can use the Edge Impulse CLI, and if you want to collect data from different sensors (like accelerometers or proprietary control systems) you can do so in a few lines of code.
To classify data (whether this is from the camera, the microphone, or a custom sensor) you'll need a model file. This model file contains all signal processing code, classical ML algorithms and neural networks - and typically contains hardware optimizations to run as fast as possible. To grab a model file:
Train your model in Edge Impulse.
Download the model file via:
This downloads the file into modelfile.eim. (Want to switch projects? Add --clean)
Then you can start classifying realtime sensor data. We have examples for:
To collect data from the camera or microphone, follow the for your development board.
To collect data from other sensors you'll need to write some code where you instantiate a DataForwarder object, write data samples, and finally call finalize() which uploads the data to Edge Impulse. .
.
- grabs data from the microphone and classifies it in realtime.
- grabs data from a webcam and classifies it in realtime.
- classifies custom sensor data.
