Overview
The LIS2DH12TR is an ultra-low-power, high-performance three-axis linear accelerometer produced by STMicroelectronics. It belongs to the ‘femto’ family and features a digital I2C/SPI serial interface standard output. This accelerometer is designed to provide a balance of ultra-low power consumption and high performance, making it suitable for a wide range of applications. The device is available in a small, thin plastic land grid array (LGA) package and operates over an extended temperature range from -40°C to +85°C.
