Integrated circuit (IC) sensors are commonly used within circuits and on PCB boards to sense and detect a wide range of parameters. They're available in a wide range of types depending on the factor that is being measured including temperature, pressure, light and movement.
ICs are extremely small with reliable performance and are used in almost all electronic devices including computers, cars, smartphones and cameras. In one integrated circuit, there can be thousands of different devices performing a variety of complex task, including multiple types of sensor. In a typical smartphone, you could find up to 14 different types of sensor providing different applications. Here are some of the most commonly used IC sensors and examples of their uses:
