A Sensor Interface is a type of hardware or software component that is used to enable communication between a given type of external sensor and an internal device or system that uses the data from the sensor. The interface can act as an interface for a sensor in an embedded system, or sensor data acquisition boards in a larger system. It allows for an input signal from the sensor to be converted into a format that can be incorporated into the device or system. Some common examples of interfaces include Analog-to-Digital Converters (ADCs) or Digital-to-Analog Converters (DACs), as well as signal conditioning components. Interfaces can also be used to convert electrical signal levels to digital signal levels, and vice versa.
