The Liquidware 3-axis accelerometer module carries an LIS302SG chip from STMicroelectronics. The LIS302SG operates in a +/- 2g sensitivity mode with less than 3mW power consumption.  This sensor is designed to operate in a wide temperature range of -40°C to +85°C. Furthermore, the LIS302SG sensor has a Sleep Mode function, ideal for use in portable, battery powered devices.  The accelerometer operates between 2.2 and 3.6V. Because of the low-voltage chips that have been damaged by 5V standard Arduino outputs, this board is equipped with built-in 5V tolerance protection.  The 3-axis accelerometer module comes as a kit with two 4-pin male headers, and is especially handy for determining sensitive changes in orientation.
