HST-D3 Assembly Tutorial

Please refer this video when you assembly the provided products

Let’s watch this

How to use


HST-D3, a combination of HST-S1 Pi and Raspberry Pi 3, transmits raw data to a PC by wired / wireless, and the raw data can be processed and analyzed by real-time storage and retrieval by PC.


The algorithm analyzed and coded by PC is able to built in HST-D3 so that user can operate desired algorithm with HST-D3 without PC.


The algorithm analyzed and coded by PC is able to built in HST-S1 Pi so that user can operate desired algorithm with HST-S1 Pi without PC or Raspberry Pi 3.
