All of these<\/strong><\/p>\n<p>A sensor is a device that detects and responds to some type of input from the physical world. The input could be light, heat, motion, moisture, pressure, or any other type of physical quantity. Sensors are used to measure and record physical quantities and convert them into electrical signals that can be read by other devices.<\/p>\n<p>Sensors can be classified into two types: analog and digital.
