SENT

The Single Edge Nibble Transmission encoding scheme, SENT, SAE J2716, is intended for use in applications where high resolution sensor data needs to be communicated from a sensor to an Engine Control Unit (ECU).

The Single Edge Nibble Transmission encoding scheme, SENT, SAE J2716, is intended for use in applications where high resolution sensor data needs to be communicated from a sensor to an Engine Control Unit (ECU). It is intended as a replacement for the lower resolution methods of 10 bit A/D's and PWM and a simpler low cost alternative to CAN or LIN. The implementation assumes that the sensor is a smart sensor containing a microprocessor or dedicated logic device (ASIC) to create the signal.

SENT is a unidirectional communications scheme from sensor / transmitting device to controller / receiving device which does not include a coordination signal from the controller / receiving device. The sensor signal is transmitted as a series of pulses with data encoded as falling to falling edge periods.
