Introduction to SENT 3.0 Interface (Single Edge Nibble Transmission) and Sensor Conditioning
SENT (Single Edge Nibble Transmission) is a unique serial interface / protocol originally targeted for automotive applications. Engineers are using this interface with sensors for applications such as throttle position, pressure, mass airflow, and high temperature. IDT provides sensor signal conditioners that function using the SENT interface.
The video reviews the three main SENT transmission protocols: fast channel read, short serial message format, and enhanced serial message format. It will cover the SENT signal basic terms, definitions and abbreviations, what is required to decode the SENT signal, and how to determine which SENT format applies to each application. It will cover the advantages of a SENT output vs. analog output, and show an example of a sensor interface using SENT 3.0.
