Motion sensors are devices that detect changes in movement and velocity. Accelerometers are a type of motion sensor used to measure acceleration along one or more of its axial directions. The BMI085 is a low-power, high-precision three-axis MEMS accelerometer module specifically designed for applications that require low power and high precision.

The BMI085 measures acceleration along its three-axes based on capacitive compensation and uses a signal conditioning circuit with calibrated zero-g offset, resulting in an output of up to 16bits. It is capable of measuring a wide range of acceleration, from static acceleration up to ±8g. It requires very low power consumption and produces low noise levels, making it ideal for battery powered applications where longterm operation is desired. The device also features a temperature-compensated voltage reference IC, minimizing its effect on power consumption.

The BMI085 provides a variety of functions for motion sensing applications. It measures acceleration in all three axes and contains a signal-conditioning circuit with a low-pass filter and adjustable outputs. The accelerometer can be used to measure the angle of a surface, detect changes in gravity, or measure shock and vibration levels. It is also capable of detecting motion or positional changes.

The BMI085 can be used in a variety of applications. The device is well-suited for mobile devices such as laptops, PDAs, or mobile phones. It can be used in medical or gaming systems to measure acceleration or vibration. It can also be used as an automotive sensor to detect acceleration and vibration levels in vehicles. Furthermore, it can be used in robotics applications for motion tracking and orientation control.

The BMI085 accelerometer module works by measuring the changes in capacitance between two electrodes. When an acceleration is applied to the device, the displacement of the electrodes changes, which results in a change in capacitance and, consequently, a change in the output voltage. This output voltage can be used to measure both the acceleration and angular rate.

The BMI085 features adjustable scaling or sensitivity which allows it to be used with different accelerometers with different ranges of acceleration. It also includes an internal temperature compensation circuit and a power-down mode to minimize power consumption during periods of low activity.

The BMI085 accelerometer module is a compact and low cost solution for precise motion sensing applications. Its low power consumption and high precision make it an ideal choice for battery operated applications while its temperature compensation circuit and adjustable gains ensure its reliability even in the most extreme conditions. With a wide range of applications, the BMI085 is a versatile accelerometer module that provides excellent performance in motion sensing applications.
