CMOS sensor
A CMOS sensor (Complementary Metal-Oxide-Semiconductor) is an image sensor used in digital cameras and other imaging devices. It converts light into an electrical signal using individual pixels made of transistors and capacitors.
What does CMOS Sensor mean?
A CMOS (complementary metal-oxide-semiconductor) sensor is a type of image sensor that uses CMOS (complementary metal-oxide-semiconductor) Technology to convert light into an electrical signal. CMOS sensors are used in a wide variety of applications, including digital cameras, camcorders, and medical imaging devices.
CMOS sensors work by Converting light into an electrical charge. When light strikes a CMOS sensor, it generates a small amount of electrical charge. The amount of charge generated is proportional to the intensity of the light. The charge is then converted into a voltage by a transistor. The voltage is then amplified and sent to an Analog-to-Digital Converter (ADC). The ADC converts the voltage into a digital signal that can be processed by a computer.
CMOS sensors are important in technology today because they offer a number of advantages over other types of image sensors. CMOS sensors are relatively inexpensive to manufacture, they have a low power consumption, and they can be integrated with other electronic devices. CMOS sensors are also very sensitive to light, which makes them ideal for use in low-light conditions.

History
The development of CMOS sensors began in the early 1970s. The first CMOS sensor was developed by Carver Mead and Lynn Conway at the California Institute of Technology. Mead and Conway’s sensor was a simple device that could only detect the presence or absence of light. However, their work laid the foundation for the development of more sophisticated CMOS sensors.
In the 1980s, researchers at the Jet Propulsion Laboratory (JPL) developed a CMOS sensor that could be used to create images. This sensor was used in the cameras on the Voyager 1 and Voyager 2 spacecraft. The Voyager cameras were the first to send back images of the outer planets.
In the 1990s, CMOS sensors began to be used in consumer electronics devices. The first Digital Camera to use a CMOS sensor was released in 1994. CMOS sensors quickly became the dominant type of image sensor used in digital cameras. Today, CMOS sensors are used in a wide variety of applications, including digital cameras, camcorders, and medical imaging devices.
