 ### Collecting data from other sensors
 
-To collect data from other sensors you'll need to write some code to collect the data from an external sensor, wrap it in the Edge Impulse Data Acquisition format, and upload the data to the Ingestion service. [Here's an end-to-end example](https://github.com/edgeimpulse/linux-sdk-python/blob/master/custom/collect.py).
