Proximity sensors
this is a slide based on proximity sensors, its types,and its application.
A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.
A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a capacitive proximity sensor or photoelectric sensor might be suitable for a plastic target; an inductive proximity sensor always requires a metal target.[citation needed]
Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between the sensor and the sensed object.
Proximity sensors are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing. This is common in large steam turbines, compressors, and motors that use sleeve-type bearings.
Proximity sensors are commonly used on mobile devices. When the target is within nominal range, the device lock screen user interface will appear, thus emerging from what is known as sleep mode. Once the device has awoken from sleep mode, if the proximity sensor's target is still for an extended period of time, the sensor will then ignore it, and the device will eventually revert into sleep mode. For example, during a telephone call, proximity sensors play a role in detecting (and skipping) accidental touchscreen taps when mobiles are held to the ear.[1]
Proximity sensors can be used to recognise air gestures and hover-manipulations. An array of proximity sensing elements can replace vision-camera or depth camera based solutions for the hand gesture detection.

Applications of Nanotechnology in Food Packaging and Food Safety (Barrier ma...
Over the past few decades the evolution of a number of science disciplines and technologies have revolutionized food and processing sector. Most notable among these are biotechnology, information technology etc… and recently nanotechnology which is now constantly growing in the field of food production, processing, packaging, preservation, and development of functional foods. Food packaging is considered as one of the earliest commercial application of nanotechnology in food sector. Around more than 400 Nanopackaging products are available for commercial use. In 2008, nanotechnology demanded over $15 billion in worldwide research and development money (public and private) and employed over 400,000 researchers across the globe (Roco, M. C. et al. 2010). Nanotechnologies are projected to impact at least $3 trillion across the global economy by 2020, and nanotechnology industries worldwide may require at least 6 million workers to support them by the end of the decade (Roco, M. C. et al. 2010). Scientists and industry stakeholders have already identified potential uses of nanotechnology in virtually every segment of the food industry from agriculture (e.g., pesticide, fertilizer or vaccine delivery; animal and plant pathogen detection; and targeted genetic engineering) to food processing (e.g., encapsulation of flavor or odor enhancers; food textural or quality improvement; new gelation or viscosifying agents) to food packaging (e.g., pathogen, gas or abuse sensors; anticounterfeiting devices, UV-protection, and stronger, more impermeable polymer films) to nutrient supplements (e.g., nutraceuticals with higher stability and bioavailability). Undeniably, the most active area of food nanoscience research and development is packaging: the global nano-enabled food and beverage packaging market was 4.13 billion US dollars in 2008 and has been projected to grow to 7.3 billion by 2014, representing an annual growth rate of 11.65% (www.innoresearch.net).This is likely connected to the fact that the public has been shown in some studies to be more willing to embrace nanotechnology in ‘out of food’ applications than those where nanoparticles are directly added to foods.

Various methods can improve its accuracy to within a few centimeters.
Better motion control using accelerometer/gyroscope sensor fusion
This document discusses using accelerometer and gyroscope sensor fusion to improve motion control. It begins by reviewing a previous presentation on using only an accelerometer for motion recognition. It then describes how each sensor - accelerometer, gyroscope, and compass - measures motion differently, with strengths and weaknesses. The main idea is to use a gyroscope to compensate for the gravity component detected by the accelerometer, allowing separation of gravity from motion acceleration. This allows more accurate motion recognition compared to using just acceleration. Implementation examples and conclusions are provided on potential applications and approaches to sensor fusion.

Proximity Sensors ppt.pptx
Proximity sensors are contactless sensors that detect the presence or movement of nearby objects without physically touching them. They work by sensing electromagnetic fields (inductive), capacitance changes (capacitive), ultrasonic waves (ultrasonic), or infrared light (IR). Proximity sensors have a long service life since they have no moving parts, can detect objects in various environments and conditions, and are used in a wide range of applications including smartphones, industrial automation, and more. The ideal proximity sensor quickly and accurately detects objects without being affected by surface properties or environmental factors.

Lab 7 Sensors.pdf
A sensor is a device that detects and responds to some type of input from the physical environment and converts it into an output, usually in the form of an electrical signal, that can be measured or recorded. There are many different types of sensors that are classified based on the quantity they measure such as temperature, light, pressure etc. Sensors play a vital role in many electronic applications by providing an interface between the real world and electronic devices. Common sensors used for detection, positioning, and counting include limit switches, photo sensors, proximity sensors, and ultrasonic sensors.

Proximity sensor
Proximity Sensor Detects An Object When The Object Approaches Within The Detection Range And Boundary Of The Sensor. Proximity Sensor Includes All The Sensor That Perform Non Contact Detection In Comparison To Sensors Such As Limit Switch, That Detect The Object By Physically Contacting Them. It is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a capacitive or photoelectric sensor might be suitable for a plastic target; an inductive proximity sensor always requires a metal target. The maximum distance that this sensor can detect is defined "nominal range". Some sensors have adjustments of the nominal range or means to report a graduated detection distance. Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between sensor and the sensed object. Proximity sensors are commonly used on smart phones to detect (and skip) accidental touch screen taps when held to the ear during a call.[1] They are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing. This is common in large steam turbines, compressors, and motors that use sleeve-type bearings. A change in the sensor's electric or magnetic field can also be used to determine proximity.
