This is a technical manual for LIS331DL MEMS motion sensor, which is a three-axis ±2g/±8g smart digital output “nano” accelerometer. It has 2.16 V to 3.6 V supply voltage, 1.8 V compatible I/O, <1 mW power consumption, ±2g/±8g dynamically selectable full-scale, I2C/SPI digital output interface, programmable interrupt generator, embedded click and double click recognition, embedded free-fall and motion detection, embedded high pass filter, embedded self test, 10000 g high shock survivability, ECOPACK® RoHS and “Green” compliant features. It can be used for free fall detection, motion activated functions, gaming and virtual reality input devices, vibration monitoring and compensation etc.
The LIS331DL is a low-power, three-axis linear accelerometer belonging to the "nano" family of ST motion sensors. It features a dedicated sensing element and a CMOS interface circuit, capable of detecting accelerations with an output data rate of 100 Hz or 400 Hz. The device supports dynamically user-selectable full scales of ±2g and ±8g and includes smart embedded functions such as click, double click, free-fall, and motion detection.
