Zener Diode is the diode which lets current flow in both the directions i.e. from anode to cathode and cathode to anode. It does not breakdown in reverse direction unlike normal diodes and thereby it operates reliably in devices. They are used to regulate stabilized power supplies, provide low power supplies from high voltages and protect the circuit from high voltages.

A valve controller is used to keep the regulated process variable as close as possible to the desired set point and also for manipulating the flow of gases, fluids, water, steam and others to compensate for the load disturbance. They help in improving the overall performance of the process by enhancing productivity and reliability and thus are the most important part of any process control loop. 

UV air purifiers work by emitting short-wave ultraviolet light. UV air purifiers are intended to identify germs and particles in the area where they are installed, such as bacteria, molds, and viruses. UV air purifiers also improve air quality. UV air purifiers are desirable due to the time-saving ability to clean shelves, TVs, and other areas where dust can accumulate. The manufacturing of UV air purifiers focus on the sensitivity of the UV air purifiers, which provide more accurate result.

Traffic sensor is an electronic sensor or timer that indicates presence and passage of vehicles with a view to direct and monitor traffic flow. Traffic sensors are primarily used in smart traffic monitoring systems to analyze pattern of moving vehicles and their interaction in traffic as they have high accuracy as well as precision in detecting vehicles. 

A thermal printer is a printer that uses heat to produce image on paper and has become increasingly popular, owing to high print quality, and is mostly used in retail, airline, entertainment, banking, grocery, and healthcare industries. In addition, thermal printing does not make use of ink or toner, but largely depends on thermal papers to produce good quality images. 

A text-to-speech is also called read aloud technology. It is an assistive technology that is used to reads the words from smartphone, computers and any other digital platform. It is a software-based technology. It is popular among individuals with reading disabilities. It provides contribution in learning, increasing literacy rate ,these factors make useful technology for the market. The manufacturing companies of text-to-speech are now focusing on increasing the sensitivity of text-to-speech, which will provide more learning and understanding text benefits. This development will help text-to-speech to penetrate more in the market.
