What is a sensor?
A device that receives and responds to a stimulus or signal. Sensors measure real-world conditions, such as heat or light, and then convert this condition into an analogue or digital representation.

What is CMOS?
Complementary Metal Oxide Semiconductor, or commonly referred to as CMOS, is a type of IC which includes microprocessor, microcontroller, static RAM and other digital logic circuits.
