Different types of applications require the use of a specific sensing technology. The main working principle of a position sensor is to measure the displacement of an object with reference to its initial position. Machines rely on sensors for the accuracy of measuring and responding to movements. Sensors are widely used in many industries. Some examples include agriculture, manufacturing, and even small consumer electronics.
A specific type of sensor that is widely used in gadgets and appliances is a tilt sensor. This is often described as a tilt switch or a rolling ball sensor.
Tilt sensor description
To understand what a tilt sensor looks like, it is described as having a cylindrical cavity, or some kind of cavity regardless of the shape which consists of a rolling ball, blob or mercury, or conductive free mass. On the other end of the sensor, there are conductive elements such as poles. When the sensor is positioned downwards, the mass inside the cylinder will roll into the poles and create a short. This will then become the switch throw for the device.
In the past, most tilt sensors were made with mercury, but this has now been mostly eliminated for safety purposes. Tilt sensors have a simple working principle and are easier to use than other types of sensors producing the same result.
Key specifications
There are several factors that influence how a tilt sensor functions. These factors include resolution, measuring range, noise tolerance, sensitivity, number of axes, and vibration. The number of axes, for example, has a big impact on the application of tilt sensors. Specifically, if a tilt sensor will be used in a game controller, it needs to have three axes, while only two axes are required if a tilt sensor is to be applied in robotics.
Advantages of using tilt sensors
Tilt sensors have some key benefits which make them desirable for various applications. These sensors are compact and easy to use. In spite of their size, they have high accuracy and resolution in reading. Also because they are compact, they cost less to produce. They also use less power and thus are more energy-efficient.
Practical applications of tilt sensors
To understand better how tilt sensors are applied, here are some specific examples:
- They are used in mobile phones to determine the angle at which the device is held with reference to its auto-rotate feature.
- They are used in game consoles and game controllers to determine the position at which the device is held.
- To show the roll movement of boats and aircraft.
- When applied in satellite technology, it is used to measure the tilt or angle of the antenna as it points towards a satellite.
Tilt sensors are practical and versatile. Not many people understand the working principle of these compact devices and how they affect our day to day lives.
With more electronics gearing towards further innovation and smarter technology, sensors are bound to adapt to the demand and move forward with technological developments to cater more effectively to the needs of industries.
