Evaluation Boards - Sensors

The CMA3000-A01 PWB is an evaluation board used for sensing acceleration along X, Y, and Z-axes, higher level vibration, and being used in electronic equipment design. The CMA3000-A01 PWB is commonly used for motion tracking, motion control, and instrumentation when small size, low power consumption, accurate measurements, and non-interference operation is of maximum importance.

The main body of the CMA3000-A01 PWB is a piezoelectric sensing element. It includes three force-transducer elements inside the package. It is a low-mass, single-axis accelerometer with an integrated ASIC ( Application Specific Integrated Circuit ) that supports two full-scale ranges of integrated acceleration from 0 to 3g and 0 to 16g. It features an I2C-compliant digital output interface that allows the on-board processor to access and control the measurements being taken. The CMA3000-A01 PWB is made in a tiny hermetically sealed package, with an overall size of only 0.3 cubic inches.

The CMA3000-A01 PWB supports several application fields including automotive applications, medical instrumentation, industrial safety systems, and consumer electronics. It is designed for operation in harsh environments, making it ideal for monitoring shock waves and vibrations in industrial sites, automobiles, or medical devices. The CMA3000-A01 PWB is also used in the aerospace industry for vibration monitoring and assessment of other parameters.

The working principle of the CMA3000-A01 PWB is based on piezoelectric effect, which is the electric charge generated by mechanical stress or force applied to a certain material. When mechanical stress or force is applied to the sensor element, the electrical charge generated is proportional to the applied force. This electrical charge is then detected by a voltage measurement circuit and converted into an electrical signal. This electrical signal is then digitized and sent through an I2C interface to be used by a processor. In this manner, the CMA3000-A01 PWB is able to measure and detect extremely small changes in relative force, acceleration, or vibration.

The CMA3000-A01 PWB also has several controller and debugging options available, including an optional USB-I2C interface adapter. This adapter allows the CMA3000-A01 PWB to be connected to the computer and allows full control with debugging and analysis of the captured data. This also provides a much easier way to use the board in a laboratory or development environment.

Overall, the CMA3000-A01 PWB is a low-power, accurate, and reliable measurement board used in a wide variety of different applications. Its integration of piezoelectric sensing elements, I2C interface, and optional USB-I2C interface adapter make it an ideal choice for applications that require accurate and reliable measurements.
