Sensors are the interface between the physical world determined by the laws of physics (i.e., mass, acceleration, conductivity, force, magnetic fields, etc.) and the digital world, which interprets the information that sensors provide for use in a wide range of products - from embedded Internet of Things (IoT) devices to smart phones to even the common household toaster. Because there are so many types of sensors available today, it would be a challenge to discuss all of them in one learning module. Since electronic design engineers often work with very compact integrated circuits (IC), this learning module will focus on some of the essential IC sensors in use today.
