They find use in in a wide range of applications in which air quality is crucial. Energy, automotive, mining, and cement industries are the major sectors where air filters are extensively used.

Smoking cessation products such as NRTs and e-cigarettes have proved useful in reducing the numbers of smokers worldwide. They can also be used to reduce smoking. The global smoking cessation products market is growing at a rapid pace and will register a CAGR of 18.16% during the forecast period. The Americas was the major revenue contributor in 2015, accounting for 46.99% of the overall revenue of the market, followed by EMEA with 39.97% and APAC with 13.04%.

The basic components of a radar include transmitters, duplexers, receivers, radar antennas, and indicators. A radar system is capable of transmitting microwaves simultaneously in all directions and thus, determines the properties of flying objects within their range. It uses radio waves to track and determine the velocity, range, and angle of objects and it is widely used in detecting aircraft, spacecraft, ships, guided missiles, weather information, and terrain.

Indoor farming is gaining popularity worldwide to meet the rising demands for food. Underutilized warehouses or multi-story buildings are converted into indoor farming facilities for mass production of crops and vegetables in racks that are stacked in layers. This is also called vertical farming and is expected to transform the agribusiness as it is going to reduce the need for cultivation land.

A micro-mobile data center is a small self-contained system designed to be a single rack enclosure that houses IT infrastructure with additional support infrastructure such as power and cooling systems. These data centers can support IT load of around 10 kW and are suitable for branch office operations and edge computing purposes.

In the event of a power outage, a UPS system is used to power the data center infrastructure until a generator takes control of the system. UPS systems are triggered automatically when the power supply is interrupted between the mains and the equipment. These systems prevent damage to the data center infrastructure and protect the facility during power sags and surges. They are generally used for short periods, ranging from a few seconds to minutes.

Optical sensors are devices that convert light or infrared rays into electronic signals. They can function in the presence or absence of light or infrared spectrum and form a part of a large electronic system. A signal from an optical sensor is analyzed or interpreted in different ways to detect the presence of a person, capture an image, or determine the position or movement of an object. The global optical sensor market grew at a CAGR of 9.7% over the last five years. Vendors in the market are investing significantly in R&D of these sensors due to the following advantages.

A robot performs multiple complex tasks with high speed, precision, and accuracy. Robots are classified into industrial and service robots. Service robots are segregated into defense, agriculture, medicals, and logistics robots and domestic machines – based on the area of application. Manufacturers, FMCG players, and e-commerce operators use logistics robots inside and outside warehouses and production plants.

Satellites transmit data and information in the form of images, which are then collected for analysis. The information thus gathered can be used to monitor and predict weather changes, disasters and natural calamities, oil and mineral deposits, availability of water sources, and climate patterns. Satellite-based EO involves the gathering of vital information pertaining to the Earth's system through remote sensing satellites.

The global sensor module market in the automotive sector generated a total of $56.67 billion in revenue in 2015 and is expected to contribute $76.12 billion in revenue to the market by 2020, growing at a CAGR of 6.08% during the forecast period. In 2015, APAC was the largest revenue-generating segment for most vendors, and it is expected to expand at a CAGR of 7.16% during 2015-2020. The powertrain and engine control segment was the largest application segment of the market in 2015, accounting for 76.8% of the market, followed by the safety and chassis control segment with 20%. The sensor module market is expected to grow during the forecast period due to high demand for sensors.

Since 2012, technological innovations have improved image resolution, increased energy efficiency, and decreased space constraints with the development of portable Pico projectors. The emergence of light projectors has ensured that even small portal projectors can display images and videos with increased clarity. Further, embedded Pico projectors are likely to dominate the Pico projector segment owing to the growing demand for flexible devices, which consume less space and are priced low. Embedded Pico projectors are becoming an important platform for augmented reality, the latest technology in electronic devices.

Ultrasonic sensors are transceivers that send and receive ultrasonic waves. They interpret the time taken by an echo to reflect back from an object using the speed of sound as the parameter. These sensors are quite immune to environmental influence, have the ability to detect almost any material, and are not affected by problematic surfaces. They can also meet diverse application requirements such as material handling, fill-level measurement, processing and hygiene detection in food and beverage processing, guiding mobile equipment in industrial scenarios, detection of doorways, medical devices, and gates and assisted parking in automobiles.

RF filters help restrict signals in the MHz to GHz frequency range. They are used in applications such as communication across the entire spectrum of bandwidth frequencies.

Fiber lasers are used for materials processing applications such as cutting and welding, marking, and fine and micro processing of components in the automotive, manufacturing, consumer electronics, and heavy industry sectors. They are also being used extensively for medical applications and R&D purposes.

Smart cards are pocket-sized cards that are embedded with integrated circuits. Smart cards can be used in many sectors such as banking, financial services, and insurance (BFSI); transportation; government; and healthcare for identification and authentication. They provide individuals with authorized access to secured premises of an organization to ensure data security and confidentiality. Smart cards are used for various applications such as payments and transit ticketing.
