The LIS332AR is a MEMS motion sensor with a 3-axis ±2 g analog-output ultracompact accelerometer. It is suitable for tilting applications, free-fall detection, gaming, anti-theft systems, inertial navigation, and motion tracking. The product features single voltage supply operation, high stability over temperature, ratiometric output voltage, power-down mode, embedded self-test, and 10000 g high shock survivability.
The LIS332AR is a miniaturized, low-power 3-axis linear accelerometer from STMicroelectronics, part of the “nano” family. It features a sensing element and an IC interface that provides an analog signal to the external world. The device is designed for applications such as tilting, free-fall detection, gaming, and inertial navigation.
