What is work of image sensor in the Robotics technology
For the digital acquisition of an image, there are two kinds of image sensors, which include CCD and CMOS. Both have a similar imaging quality. However, there is a significant difference in their key functions and other features. The charge-coupled device (CCD) image sensor is based on an analog system. The charge reaching the CCD edge is transmitted to a digital or analog converter that converts the charge into a digital value for each pixel. CMOS sensors are more efficient in generating a digital image and consume less power than a CCD. They can be larger than a CCD, enabling high-resolution images, and their manufacture is more economical when compared to a CCD.
What is work of relay in the Electrical.
A electrical relay is an electronically operated switch that is remotely activated by an electromagnet which pulls a set of contacts to either make or break a circuit. Electrical relays are commonly used for switching signals, radio frequencies as well as high current circuits.
