Temperature Sensor Insights and Types

You may not know it, but temperature sensors are present throughout many of the daily tasks in our lives. Discover how monitoring and regulating temperature is clearly fundamental to human life.


Thinking back on your day today – did you turn on the kettle for a cup of coffee or take the milk out of the refrigerator? Did you take the train to work or have you charged your phone battery? These tasks, and more, all use temperature sensors – even the computer you may be using now depends on a temperature sensor! Monitoring and regulating temperature is clearly fundamental to human life, and creating the technology to achieve this has been the work of many great scientists. Galileo invented the first documented thermometer in 1592, using a simple air system in a glass bulb. It wasn’t until the 18th century that Daniel Gabriel Fahrenheit created the more accurate mercury thermometers, and Anders Celsius introduced the 0-100 degrees calibration references that we all know of today. Fast forward to now, and we see many types of advanced temperature sensors available with different technologies and designs. New inventions such as the thermistor, thermocouple, thermopile, digital and platinum sensors all offer a wide range of benefits for different situations and environments. They have become highly sophisticated devices that help people throughout many facets of life: in factories, hospitals, schools, homes and more.

Nowadays, there is a huge market for temperature sensors: it was valued at USD 5.13 billion in 2016 and is estimated to grow by 4.8% until 2022, reaching USD 6.79 billion for the entire temperature sensor market. This is fueled by changing consumer and industrial trends, and technological shifts that place new demands on temperature sensors and drive innovation. Many producers, such as in the high-tech automotive and semi-conductor sectors, need advanced temperature sensors to better run their production facilities, such as for energy efficiency and automated process control. To manage this, temperature sensors must be smarter with precise communication and self-diagnostic functions. Meanwhile, as electronic devices become slimmer and more portable, it is a challenge for engineers to create corresponding designs for temperature sensors. Standing at the center of this dynamic industry is TE Connectivity – one of the largest sensor technology companies in the world. With a broad product portfolio and an experienced team of engineers, they are wellplaced to meet the needs of the marketplace. While TE Connectivity’s sensor technology is undoubtedly impressive, what gives them most pride is seeing how this technology is applied across multiple industries, and how it helps people every day in their jobs and in their lives. When looking at TE Connectivity’s product portfolio, you’ll find that there really is something for all scenarios.

Temperature sensors are one of the most widely applied technological devices in the world – helping people in many unique ways. Whether you are sipping your coffee while reading newspaper in your home, or navigating your car through the city to get to your office or even simply sitting in your office comfortably enjoying the “right” temperature as you type through your daily work, you may not always notice them in your life because they secretly monitor all temperature around you to ensure everything will function properly with appropriate temperature range, but you would certainly notice them if they were gone! TE Connectivity is proud to be a part of this story, and to offer a wide range of temperature sensor products to meet your needs.
