Overview
The IIS2DHTR, produced by STMicroelectronics, is an ultra-low-power high-performance three-axis linear accelerometer. It features a digital I2C/SPI serial interface and is designed for a wide range of applications, particularly in industrial and IoT sectors. The device is known for its low power consumption, down to 2 μA, and its ability to measure accelerations with output data rates from 1 Hz to 5.3 kHz. It is available in a small thin plastic land grid array package (LGA-12) and operates over an extended temperature range from -40 °C to +85 °C.
