The overwhelming need for machines to make life easier fuels the demand for technological advancements. There is no shortage of innovative developments in transportation, communication technology, medicine, and industrial machines. In many of these applications, sensors are an integral part.

Sensors measure the displacement of an object in relation to a reference point. Imagine how important this is in making cars, aircraft, trains, and boats much safer. Sensors are also used in many industrial machines relevant in construction and mining; such as forklifts, and backhoes. Production and efficiency are increased with the use of these machines.

What is the Basic Working Principle of a Sensor?

Position sensors are often categorised by the type of movement. Does the machine move back and forth? Is the movement at an angle or tilt? An angle sensor or rotary sensor calculates the orientation of an object with respect to a reference position. This is expressed by the number of rotations necessary to change from one position to another around an axis.

To better narrow down the options for choosing the type of sensor used in a specific application, there are parameters that need to be considered. Sensors are further categorised according to output type (analog, digital, ratiometric), or sensing range (±500 °, ±100 °, ±60 °, 360 °). These are only a couple of the parameters since there are several others that would need to be looked into.

What are the Most Common uses of Angle Sensors?

Angle sensors and other types of sensors are indispensable devices used for many applications. Some examples include:

  • Float level sensing
  • Throttle position sensing
  • Transmission gearbox encoding
  • Power seat position sensing
  • Power mirror position sensing
  • Pedal position sensing
  • Steering wheel position sensing
  • Headlight position sensing

These are some of the most identifiable uses of sensors. Cars and other automotive vehicles require sensors for certain features and functions.

Revolutionary Modern uses of Sensors

For many decades now, sensors have been instrumental in industrial machines. There is also a growing need to look for other applications that can help revolutionise other areas. One example is robotics. In recent years, you may have noticed the proliferation of robots and drones. Robots are being explored not only for industrial uses but to perform functions relevant to a person’s daily life. There has been a recent obsession and trend in manufacturing robots that can perform mundane functions and humanoid motions. This is significant and astounding as robots can be used to further automate even the most basic activity!

Aside from robotics, sensors are also being used in making artificial prosthetics. This is remarkable in terms of making the lives of paraplegics better. Prosthetic limbs can be manufactured to have greater mobility and function. These can even be made to have more lifelike movements.

There are still more avenues to explore in using sensors for greater technological advancements in our modern society. Indeed, the existence of sensors for many decades now does not limit the possibilities for new advancements in the versatility of their use.
