Accelerometer: The Best Way to Assess the Force

The modern world is developing at a faster rate with the invention of new technologies. Electro mechanics is one of the major fields in the field of mechanics. Accelerometer is one among them that is used to find out the rate of acceleration force. It find outs the forces regardless of static or dynamic.
You may be wondering that how it could be useful. By assessing the static acceleration, you can locate the device and position on earth. You can find out the dynamic acceleration to analyze the path of movement of the device. Nowadays, accelerometers are used for many purposes world-wide. They are used for analyzing the quality of car engines.
In the world of computers, the scientists have invented a new method to safeguard the laptop from damages while falling. If you happen to drop your laptop accidentally, this device will detect the fall and it will switch off the hard drive. Moreover, this electro mechanic device is used in the safety features of cars for deploying airbags at the right time.
They work in different ways like piezoelectric effect in which the microscopic crystal is used to stress the accelerative forces that gives voltage. It can be also created by sensing the changes in capacitors. There are more methods available like hot air bubbles, and light.
Before buying an accelerometer you have to look into different aspects. Some of them are:
1. You have to analyze which device you need like analog output or digital output. It purely depends upon the hardware you use. If your hardware is a basic stamp, you need a digital output whereas if you are using PIC, AVR, OOPIC, or Javelin, then you will require an analogue one. But an analog device is always better to prefer since it is the best.
2. For all purposes, 2 axes are good. But, if you prefer 3D positioning then, you have to go for 3 axis or 2 axis with right angle mounted accelerometer.
3. In general, more sensitivity is preferable since you get a more accurate reading. This is because it there is a certain change in the acceleration, a larger difference will be there in the signal and larger signal differences are easy to measure.
4. You can choose a ±1.5g accelerometer if you want to measure only the gravity of the earth. But you have to go for higher ones according to your needs.
5. You have to choose the bandwidth according to your purpose. If your work is very slow moving application, you need only very low bandwidth. On the other hand, if your work is heavy, then you can go for higher bandwidth.
