Motion sensors and accelerometers are important devices for systems that involve human motion. They are used for measuring acceleration of a body in three spatial axes x, y and z. The ADXL327BCPZ-RL7 is a good example of a tri-axis accelerometer which is capable of measuring both dynamic ratio of acceleration as well as static acceleration. This device is used in diverse applications that involve motion sensing.

Applications

The ADXL327BCPZ-RL7 accelerometer is a key component of automotive safety systems such as airbag controllers and seat belt locking systems. It is used for sensing impacts and triggering the safety system to deploy when required. This accelerometer is employed in automotive safety operation as well as in monitoring the health of the vehicle by detecting the variations in acceleration that could indicate the onset of a malfunction.In the industrial automation sector, this device is used in automated material handling systems, such as conveyer systems. The acceleration data is used for driving motors, turning of rollers or in any other application where a change in motion needs to be automatically monitored and controlled.The ADXL327BCPZ-RL7 is also used in UAVs (Unmanned Aerial Vehicles) for autonomous motion. Here the accelerometer is used for detecting changes in the direction of motion for navigation purposes.In addition to these primary applications, the ADXL327BCPZ-RL7 is also used in consumer electronics such as laptops, tablets, smartphones etc. These devices primarily employ the device for providing input data to on-screen motion sensing. In gaming consoles, the data from the accelerometer is used for providing motion gaming experience.

Working Principle

The ADXL327BCPZ-RL7 accelerometer consists of a sensing element and a signal conditioner. The sensing element is generally a thin film bulk micromachined sensor containing proof mass and an outer frame. When a motion is detected, the inertia of the proof mass causes a resistance to the change, causing the proof mass to deflect proportionately to the acceleration. This displacement is sensed by the sensing element, which is then converted to an analog signal using an associated external circuit. This signal is then amplified and processed by the signal conditioner, which in turn produces a change in internal voltage.

The accelerometer is typically mounted onto a PCB with appropriate connectors for connection to the external circuitry. The signal from the accelerometer is generally transmitted to a microcontroller. This signal is then processed to detect the intensity and direction of the acceleration. The output from the accelerometer gives the acceleration in three dimensions, each corresponding to an axis of the accelerometer.

The ADXL327BCPZ-RL7 accelerometer has a wide range of uses in various motion sensing applications. It is a robust device that is capable of accurately measuring dynamic and static acceleration in all three directions. The device is ideal for applications that demand reliable operation and high accuracy. It is also known for its cost effectiveness and its simple set up procedure.
