Why We Can’t Live Without Sensors



Do you know how important and prevalent sensors are to our environment? Sensors can be found everywhere performing multiple tasks. Sensors are used in commercial, industrial, and personal applications. They come in all shapes and sizes from motion detectors that signal the employment of lights to counters that signal radiation loss.

What sensors do

Sensors’ main purposes are to alert a person or system. It may be in order to generate a new function or to signal a problem. A majority of sensors regulate and control existing operations. For instance, various speed and position sensors assist in automotive engine management. Adjustable linear and output current sensors monitor AC or DC current for different electrical or industrial systems. Proximity sensors aid in aircraft and marine applications.

Multiple uses of sensors

Other sensor types include photoelectric sensors for detecting objects with light; liquid level sensors and debris monitors used for aircraft; and temperature and pressure meters which work with industrial, commercial, medical, and processing systems. Places visited, our means of transportation, the mechanisms that surround us, etc. are affected by sensors. We rely on sensors regularly as part of engaging in our everyday lives.

Thermometers and barometers indicate the weather, oil and fuel gauges keep cars running, and proximity sensors turn lights on and off. Think about the operations that we take for granted like automated doors, elevators, ovens, and refrigerators. They all incorporate the use of sensors into our lives, making sure pathways stay open, food stays fresh, and appliances are dependable.

The future

Sensors will play a major part in our futures. Smart homes are already prevalent in the Eastern hemisphere and will soon become more so in the United States. Think about living in a home that virtually takes care of itself. Wakeup and the shower will know what temperature to make the water, lights will know what level is most comfortable, T.V. and radio volumes will understand what volumes are reasonable for you, the thermostat will know when to lower and higher itself, etc. The future will be a place of efficiency and convenience due to sensor technology.


We would not be able to live with as much ease without the existence of new technology. Sensors have already brought us a long way and will continue to facilitate a technologically savvy future. Sensors are making the way we do things bigger, better, and more convenient. Where would we be without them?
