Wikipedia

  1. Detect

    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 detect in a Sentence

  1. Godri Pollitt:

    We want to go a step before that and be able to start thinking about, do we need more infectious control measures in place, do we need less people in this space? Do we need more ventilation? and also thinking about if people are at a potential risk for being infected? If we detect it within the air, there’s a good chance that maybe those people are at risk and should be quarantining.

  2. Kevin Hrusovsky:

    Nobody thought that many of the proteins or bio markers that affect the brain would even be in blood. It was thought, basically, that those proteins and those markers would only be in the brain in the spinal fluid, but what we’ve learned is that a small amount of the spinal fluid, the cerebral spinal fluid, actually leaks into the blood through the blood brain barrier and because our technology can detect things that are so minute in blood, we can test what’s going on in the brain.

  3. Getty Images:

    But nobody expected to directly detect one like this because we didn't expect them to be so bright. Somehow it's converting magnetic energy to radio waves much more effectively than anything we've seen before.

  5. Gwen Landt:

    Gwen Landt said. Gwen Landt added that Gwen Landt is trying to give tips to people on when its best to help these animals and when they should be left alone. Rescuers believe the beautiful fawn was separated from Gwen Landt mother and hit by a car which snapped her right back leg just below the hip bone. ( Credit : SWNS) When the mama is taking care of her baby, she leaves it in the ground and it curls up like a little croissant so the mother can go off and find food, she leaves the baby because it doesnt have any scent for a predator to detect. People often come across the baby deer and they think, Oh, it doesnt have a parent, Ill rescue it. But they should wait to see if the mother comes back.
