nRF Edge Impulse Mobile app

Integrated machine learning (ML) from Edge Impulse directly on the Thingy:53

nRF Edge Impulse app is developed in collaboration with Edge Impulse to train and deploy embedded machine learning models on the Nordic Thingy:53 using Edge Impulse Studio.  Every Nordic Thingy:53 comes pre-installed with firmware compatible with the nRF Edge Impulse mobile app. The app allows you to upload raw sensor data via your mobile device to the cloud-based Edge Impulse Studio and deploy fully trained ML models to the Nordic Thingy:53 over Bluetooth® Low Energy (LE).

The app allows you to choose between existing projects in Edge Impulse studio data or creating a new project and can collect sensor data from the following set of sensors on the Nordic Thingy:53:

  • Accelerometer
  • Microphone
  • Magnetometer
  • Light
  • Temperature, Pressure, Humidity and Air quality
  • Inertial (Accelerometer and Magnetometer)
  • Light and Environment
  • Light and Inertial
  • Environment and Inertial

The collected sensor data can be labeled as training or testing data and may be inferenced directly in the app with machine learning model deployed to the Nordic Thingy:53.

A free Edge Impulse account, which can be created from the nRF Edge Impulse app or at www.edgeimpulse.com, is required to connect the app with Edge Impulse Studio.
