In today's complex aircraft, sensors are everywhere. Gathering data is critical. Typically, analog transducer measurements are passed through an ADC, manipulated by a microcontroller, and passed to a communication protocol device for transmission on an avionics data bus. The microcontroller requires code, which increases design time, cost and certification complexity. This paper introduces a new device which provides a way to autonomously transmit sensor data over an ARINC 429 avionics data bus and completely eliminate the requirement for an MCU or software.
