Abstract
In this paper, we present a filter circuit that can be used to prevent sensor disturbances caused by intentional electromagnetic interference (IEMI). Sensors are an increasingly important component in almost all electrical systems, and faulty sensor readings can cause major problems. We show that sensor disturbances can be caused by IEMI and that sensors with Inter-Integrated Circuit (I²C) interfaces are particularly susceptible to this type of interference. We present a filter circuit that can be connected directly to I²C sensors in order to prevent disturbances caused by IEMI. Through both simulation and experimental testing, the effectiveness of the filter in preventing errors in sensor readings without impacting the functionality of the I²C communication is demonstrated.
