A motion sensor or accelerometer is a device that detects or measures changes in its environment. The MMA3204KEG is a low-power, high-sensitivity accelerometer with an integral temperature compensation from Freescale Corporation. It provides a wide range of motion-sensing capabilities for applications such as tilt and vibration measurements, vibration isolation, mobile phone designs, gaming devices, digital cameras and more.

The MMA3204KEG is a MEMS-based accelerometer with four differential outputs that generate voltage pulses proportional to tilt or vibration. The integrated temperature measurement compensates the output for temperature variations. It has a total range of ±5 g, a full-scale range of ±2 g, and a low-power sleep mode for improved battery life. The device is available in 8-pin LGA package and can be operated over a wide temperature range 0°C to +85°C.

The MMA3204KEG accelerometer requires no external components and its small footprint design makes it ideal for small form factor applications. The device provides high linearity in the full-scale range of ±2 g and it has low-noise floor measurements of less than 50 μV/GRMS. It is a self-test single-axis accelerometer suitable for both applications that require a low, drift and small size.

The MMA3204KEG accelerometer works by measuring acceleration and deceleration forces in both directions along the axis of the sensor. It utilizes a converter that measures the voltage produced through a functional relationship between acceleration and the corresponding output voltage. The output voltage is then fed to a microcontroller, which processes the information and performs the required calculations.

In addition, the MMA3204KEG accelerometer features a number of integrated features that allow for reliable operation in a wide variety of environmental conditions. It features a built-in high frequency rejection filter to reduce high frequency noise, and a low-noise amplifier that provides better signal-to-noise characteristics. EMI immunity is also provided for interference-resistant performance. The MMA3204KEG is ideal for a variety of industrial, automotive and consumer applications.

The MMA3204KEG accelerometer is a reliable and cost-effective motion sensing solution that is suitable for a variety of applications. It features low power consumption, high sensitivity, and wide range of motion sensing capabilities. Its small form factor and integrated EMI immunity and temperature compensation make it a perfect choice for embedded device designs and applications that require reliable measurement of acceleration and vibration.
