A sensor is a device that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena. The output is typically a signal that is converted to a human-readable display or sent to a computer for further processing. Sensors are used in many applications, ranging from everyday consumer devices to industrial and scientific instrumentation.

Sensors work by interacting with their environment in some way. For example, a temperature sensor might change its electrical resistance in response to changes in temperature. A light sensor might produce a voltage proportional to the amount of light it detects. These changes are then converted into a signal that can be measured and interpreted. The complexity of sensors varies greatly, from simple components like thermistors to highly sophisticated devices used in aerospace and medical fields.

The purpose of a sensor is to provide information about the state of the physical world. This information can then be used for a variety of purposes, such as monitoring, control, and automation. For instance, in a home, a smoke detector uses a sensor to detect the presence of smoke and trigger an alarm. In a car, various sensors monitor engine performance, tire pressure, and speed to ensure safe and efficient operation. In scientific research, sensors are used to measure extremely subtle phenomena, enabling new discoveries. The development of new and improved sensor technologies continues to drive innovation across many sectors.
