Monitoring the acceleration is important in many industries including automotive machines like cars, gaming devices, and smartphone applications, etc. Even it is necessary for many electronic projects. So, if you are seeking a module that measures vibration and acceleration, then ADXL335 3-Axis Accelerometer Module might be the right choice.
How Accelerometer Works?
Basically, an accelerometer is an apparatus that detects vibrations and accelerations. As we already know that acceleration is the change of velocity in a body or an object concerning time. So, an accelerometer senses these vibrations produced by that body and used this for the change of direction. It senses the acceleration and vibration and transforms them into pressure or stress; we know this phenomenon as the piezoelectric effect. After that, this energy is then get converted into an electrical voltage which is needed to drive the device. In other words, it transforms mechanical energy (basically, vibrations) into electrical energy.
Brief Overview of ADXL335 Accelerometer
ADXL335 is a module that takes the analog input and measures the acceleration in the three dimensions, which are X, Y, and Z. Therefore used in the construction machines like drilling machines. Also, in the human sports devices like running, walking, etc. In short, this low-power, low-noise module can easily be linked with any microcontroller or microprocessors.

Applications of ADXL335
Mobile Devices
If we talk about ADXL335 Module in smartphones, it identifies the changes in the phone’s orientation and rotates the screen accordingly. It tracks particular motions like tilting, rotating, shaking, and change the orientation.
Gaming Devices
Keyboards, joysticks and mouse has become an old school in today’s gaming world. This era uses augmented virtual reality for gaming because it facilitates controlling the motion and direction in space. So, ADXL335 has a major role in the gaming industry.
For Disk drive Protection
ADXL320 accelerometer measures axial acceleration, detects a drop, and then develops a signal that causes the drive head to be recalled to a protected zone. If this can occur before the product hits the floor or stationary surface, it will prevent a collision between head and platter.
