Industry veterans think that custom optical sensors are futuristic and will be a pivotal part of many applications in the days to come.
FREMONT, CA: It is widely believed that by the end of 2018, approximately 23 billion devices will communicate with various networks, thanks to the advent of the IoT. The increasing popularity of the IoT has also spurred the need for cutting-edge, customized optoelectronic sensor solutions.
Various optical sensors such as through-beam, retro-reflective, and diffuse reflection sensors have been extensively used in different applications over the past few years. Unlike yesteryear cables, the lack of electricity in its strong resistance to drastic temperature changes has made optical sensor communication highly preferred globally.
Contrary to usual belief, optical sensors aren’t merely objects exploited for research and development; they are embedded in devices most humans use routinely. Ambient light sensors enclosed in most mobile phones are perfect examples of an optical sensor application, which the majority of people today can relate with.
Significantly, optical sensors have revolutionized the biomedical industry. Optical heart-rate monitors, for example, have been widely used by medics across the globe.
In an ordinary optical heart-rate monitoring sensor, light reflected by the skin is caught by optical sensors. The density of blood and its capacity to absorb light supports the sensors in accurately determining fluctuations in heart rate.
Visual sensor-based liquid level indicators are also quite popular and help limit liquids to the desired levels in oil refineries. These liquid level indicators are combinations of LEDs, light transistors, and prisms, and they trigger an alert according to the amount of light reflected by the sensors.
Another advantage of optical sensing, which has gained immense popularity over the years, is DCKV (demand control kitchen ventilation) systems. These ventilation systems trigger an alert if smoke penetrates, triggering fans to operate at high speed, thus preventing suffocation significantly.
The embracement of the BYOD culture globally and the advent of technology have made optical sensors popular. Industry veterans think that custom optical sensors are futuristic and will be a pivotal part of many applications in the days to come. In the current technological climate, custom optical sensors are here to stay.
