Motion Sensors - Accelerometers

The H3LIS200DLTR is a MEMS-based linear accelerometer module manufactured by STMicroelectronics. This high-performance device provides accurate, high-resolution acceleration measurements in three-dimensional space along two linear axes and one rotational axis – simply known as x, y and z. Utilizing an anisotropic magneto-resistive (AMR) sensing element and built-in signal conditioning circuitry, the H3LIS200DLTR is capable of performing high resolution, high speed, and low-noise acceleration measurements with millisecond response times.

Application Field

The H3LIS200DLTR accelerometer has been designed for a wide variety of applications that require the highest performance and reliability. It is often used in a variety of motion-sensing applications such as safety and crash detection, navigation systems, unmanned aerial vehicles, industrial automation, consumer electronics, and gaming consoles. With its precision, speed, and power efficiency, the device is ideal for augmenting and optimizing existing motion-sensing solutions.

Due to its low-power consumption, wide dynamic range, and high accuracy, the H3LIS200DLTR is also well-suited for applications such as gesture recognition, gaming, and user interfaces that require precise motion tracking. Additionally, the device is also able to measure shock and vibration to provide fault detection and predictive maintenance data. With its user-defined acceleration range and bi-direction detection, the H3LIS200DLTR is one of the most suitable option for a variety of motion sensing applications.

Working Principle

The H3LIS200DLTR utilizes an AMR sensing element which, when placed in the presence of an external magnetic field, experiences a proportional resistance change. The acceleration along the two linear axes is deciphered using this principle. The device features user-programmable parameters to enable a range of convergence strategies: from low-power, low-noise yet slow response times, to high-power, optimally-noisy but very fast responses.

The device also features an integrated temperature sensor which allows the temperature of the system to be monitored and compensated for. Furthermore, the magnetic field strength of the external environment is monitored and can be used to accurately determine the magnitude of external acceleration being applied to a component.

In short, the H3LIS200DLTR works by using the magneto-resistive sensing principle, which is based on the change in the resistance of an AMR element driven by the external magnetic field. Through sophisticated signal conditioning, the supported linear acceleration along the two linear axes and the rotational axis is calculated, monitored, and captured.
