The LIS2DH is an ultra low-power high performance three-axis linear accelerometer belonging to the “femto” family, with digital I2C/SPI serial interface standard output. The LIS2DH has dynamically user selectable full scales of ±2g/±4g/±8g/±16g and it is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz. The self-test capability allows the user to check the functioning of the sensor in the final application. The device may be configured to generate interrupt signals by two independent inertial wake-up/free-fall events as well as by the position of the device itself. The LIS2DH is available in small thin plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
“This project uses a C8051 microcontroller development kit, an accelerometer evaluation board, and Simplicity Studio IDE—all from Silicon Labs—to rather quickly and easily build a motion-detecting alarm system.”
“I’ve always been dreaming of making a desktop clock which without complex functions, just smaller and can display time. Here is what I think: Features: Small and convenient; Inertial conduction, sensing the placement of clock; Charging Function. My clock …
