What is a BMA220 Accelerometer?

The BMA220 is a 3-axis, digital, low power, micro-machined accelerometer. It is designed for a wide range of motion sensing applications such as vibration metering and medical device motion sensing. The accelerometer features low power consumption, improved robustness to acceleration shocks and other environmental conditions, low noise, and high performance digital signal processing.

Application field of BMA220:

The BMA220 is an ideal choice for motion sensing applications, such as:

• Gaming: The BMA220 accelerometer can be used in gaming peripherals for immersive and interactive game experiences. It enables movement-based gaming experiences as it monitors and detects movement and acceleration of the gamepad.
• Wearable devices: Wearable healthcare technology is a burgeoning field and a core application of the BMA220 accelerometer is in wearable healthcare technology. Tablets, watches, and other wearable devices can acquire motion sensing data to monitor the user’s health and activity.
• Virtual Reality: The BMA220 accelerometer enables hands-free virtual reality experiences. It can detect and track acceleration, tilt angles, and rotational movement, which enhances the immersion of both stationary and dynamic virtual reality experiences.
• Robotics: Motion sensing technologies are essential for modern robotics applications. The BMA220 accelerometer improves the robot’s situational awareness in terms of acceleration, tilt, and rotational movement, allowing the robot to autonomously explore its environment with greater accuracy.

Working Principle of BMA220:

The BMA220 accelerometer is a 3-axis, digital, low-power, micro-machined accelerometer. The accelerometer works by detecting the acceleration on its X, Y, and Z axes with built-in MEMS (micro-electro-mechanical system). The built-in MEMS consists of a mass that is connected to one or more springs. When the device is moving or being accelerated, the mass moves causing a change in the capacitance of the electrodes, this change in capacitance is detected and interpreted as a change in acceleration.

The accelerometer also has two digital filters to control the response of the device to acceleration changes. A low-pass filter is used to reduce the amount of noise in the output signal, while a high-pass filter eliminates the effects of earth’s gravitational pull from the signal, resulting in more accurate measurements. The device is also calibrated to improve the accuracy of the measurements.

The BMA220 accelerometer is capable of measuring accelerations up to a range of +/-16g with a resolution of up to 0.0039g. It runs on a low power consumption of 0.87 mA during active mode. In standby mode, it utilizes only 20 µA, introducing a low power resource requirement for battery-operated devices.

The BMA220 accelerometer is a highly integrated MEMS device combining advanced signal conditioning functions, integrated filters, two selectable sample rates, and an I2C digital interface. As such, it offers an impressive combination of performance and power consumption features in a small, cost-effective package.

Conclusion:

The BMA220 accelerometer is a highly integrated 3-axis, digital, low-power, micro-machined accelerometer. It is designed for motion sensing applications, including gaming, wearable devices, virtual reality, and robotics. The device is capable of detecting acceleration up to a range of +/-16g with resolution of up to 0.0039g and has low power requirements in both active and standby mode.
