1. Sensors

   A sensor is a device that produces an output signal for the purpose of sensing a physical phenomenon. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor. Sensors are always used with other electronics. Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base, and in innumerable applications of which most people are never aware. With advances in micromachinery and easy-to-use microcontroller platforms, the uses of sensors have expanded beyond the traditional fields of temperature, pressure and flow measurement, for example into MARG sensors. Analog sensors such as potentiometers and force-sensing resistors are still widely used. Their applications include manufacturing and machinery, airplanes and aerospace, cars, medicine, robotics and many other aspects of our day-to-day life. There is a wide range of other sensors that measure chemical and physical properties of materials, including optical sensors for refractive index measurement, vibrational sensors for fluid viscosity measurement, and electro-chemical sensors for monitoring pH of fluids. A sensor's sensitivity indicates how much its output changes when the input quantity it measures changes. For instance, if the mercury in a thermometer moves 1 cm when the temperature changes by 1 °C, its sensitivity is 1 cm/°C (it is basically the slope dy/dx assuming a linear characteristic). Some sensors can also affect what they measure; for instance, a room temperature thermometer inserted into a hot cup of liquid cools the liquid while the liquid heats the thermometer. Sensors are usually designed to have a small effect on what is measured; making the sensor smaller often improves this and may introduce other advantages.Technological progress allows more and more sensors to be manufactured on a microscopic scale as microsensors using MEMS technology. In most cases, a microsensor reaches a significantly faster measurement time and higher sensitivity compared with macroscopic approaches. Due to the increasing demand for rapid, affordable and reliable information in today's world, disposable sensors—low-cost and easy‐to‐use devices for short‐term monitoring or single‐shot measurements—have recently gained growing importance. Using this class of sensors, critical analytical information can be obtained by anyone, anywhere and at any time, without the need for recalibration and worrying about contamination.

Examples of Sensors in a Sentence

1. Raymond Foster:

   [Law enforcement] could also be dropping remote motion sensors to ensure that the escapees don’t backtrack on them, some motion sensors take a picture, some report back that someone is walking in that area.

2. Eben Frankenberg:

   The more sensors you use, the better chance you have of getting it right, if your radar says it sees a duck in the road and your camera says that's a person with a walker, how do I break that tie ?

3. Matt Tait:

   Next-gen smart TVs and devices run complex software, have Internet connections, and often have integrated sensors like microphones, these features enable things like internet streaming services and voice-commands, but can unfortunately be subverted by hackers if the device gets compromised.

4. Senate Committee on Commerce:

   Sharks and the scientists who study them have led us innovations in improvements in aerodynamics, renewable energy, electrical sensors, and health and medical research. Innovative shark research can benefit marine ecosystems and continue to raise public awareness about these important species.

5. Professor Jonas Buchli:

   We have a series of sensors that we have already mounted and that we will mount on the robot, there are several sensors mounted on the robot which can measure the distance. We will mount cameras. There is an IMU (inertial measurement unit) - this is a device that can measure the orientation of the robot in space, and with fusing all this information together for the robot to know where it is in space.
