Sensors are usually defined as a well designed technical device or a machine that is commonly used to detect the changes or events that occur in the environment, and these sensors after detecting the changes transmit the signals to the interlinked electronic device such as a computer. It helps in the conversion of a physical or chemical quantity into an electrical signal.
These are commonly placed on the heavy and dangerous machine in order to detect the motion, heat, light, pressure and other changes, and this helps the operators from getting harmed or injured.
