1. detector

   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.

1. Detector

   A detector is a device that recovers information of interest contained in a modulated wave. The term dates from the early days of radio when all transmissions were in Morse code, and it was only necessary to detect the presence of a radio wave using a device such as a coherer without necessarily making it audible. A more up-to-date term is demodulator, but "detector" has a history of many decades of use, even if it is a misnomer.

Examples of Detector in a Sentence

1. Matt Dolan:

   In Massachusetts, and other places, for example, you have to have a smoke detector certificate from the fire department in order to close on your home, those inspections have been shut down for the next three weeks. That will interrupt closings.

2. Curtis Sliwa:

   Knowing that many gang members go to schools, if for nothing more [than] to recruit and sell drugs, they're going to be able to resolve their disputes in the classrooms, in the lunchrooms, within the school buildings itself, because now they won't even fear… a pat-down or having to go put their backpack through a metal detector, this is not focusing on what the real problem is.

3. National Transportation Safety Board:

   Had there been a detector earlier, that derailment may not have occurred.

4. Michael Haggard:

   The manufacturer in the manual says right there and then that you can not be over 287 pounds. Yet they don't provide a scale. They don't tell the ride operator you need to have a scale, if weight is in question, yet at this ride in Orlando, the FreeFall ride, they have a metal detector. So you go through a metal detector, which there's no risk of that associated with the ride, except maybe the keys could fall out and hit somebody.

5. Hillary Clinton:

   He took a lie detector test. I had him take a polygraph, which he passed, which forever destroyed my faith in polygraphs, oh, he plea bargained. Got him off with time served in the county jail, he’d been in the county jail about two months.
