STMicroelectronics have released some new MEMS chip type tri-axial accelerometers. The LIS3LV02DQ device is a 3-axis low-g accelerometer with a standard SPI/I²C digital interface. The LIS3L02AL/LIS3L06AL sensors have analog-outputs. The accelerometers can measure both tilt and acceleration along all three (x, y and z) axes at a very low noise level and minimized power consumption.
