Working Principle:

The PGA900ARHHR consists of three integrated inertial measurement units (IMUs), one for angular rate, one for acceleration and one for magnetic field measurement. Each of the IMU contains an accelerometer, gyroscope and magnetometer. The accelerometer is used to measure the linear acceleration in all three axes while the gyroscope measures the angular rate in all three axes. The magnetometer measures the magnetic field in two orthogonal directions. The device also contains an integrated digital low-pass filter (DLPF) to reduce noise and ensure the accuracy of the measurement.

The PGA900ARHHR provides an I2C-compatible digital interface that allows the device to be connected to an external processor. The processor can read the output signals of the device and decode the measurement data. The device also provides an SPI-compatible digital interface for connection with external sensors, if needed. The data can then be used for various applications such as robotics, automotive systems and smart phones.

The device is also highly configurable and features multiple integration options. It can be used in combination with other sensors such as pressure, temperature and humidity, to provide even more precise results. This makes the PGA900ARHHR an excellent choice for embedded systems requiring a reliable, cost-effective and precision solution.

Conclusion:

The PGA900ARHHR is a reliable and cost effective device designed for measuring angular rate, acceleration and magnetic field. It offers an integrated and low-power solution for high accuracy measurements. It is widely used in robotics, automotive systems, weapon platforms, smartphones and medical equipment. The processor-controlled interface and configurability options make it an excellent choice for embedded systems requiring precision, reliable data.
