During recent years, more and more portable devices, such as handset、MP3 and PMP, are calling for healthy and mobile features. Pedometer is an instrument that can measure human step and calculate consumed energy. Unlike traditional mechanical pedometer, a new kind of pedometer based on ADXL330 from Analog Device, is of high sensitivity, high accuracy (95%), high integration and low power consumption (3.3 mW), suitable for portable consumer electronic device. ADXL330 is 3 axis analog outputs, low g accelerometer, with 330 mV/g_n sensitivity.
