STP201M IIC Interface Embedded 3D Pedometer Module STP201M ---for Wrist pedometer products (like pedometer bracelet and watch) I. Description STP201M is a 3D pedometer module with functional IC chipset which include a G-sensor and MCU. It has adopted the standard IIC interface, with the 3D MEMS sensor (G sensor) and high precision of 3D pedometer algorithm, it can give a precisely pedometer in any direction. This chipset has the characteristics of small size, low power consumption and etc. The standard I2C digital interface ensures it can be easily embedded in various kinds of pedometer functional system Note:The algorithm of our pedometer is adjustable according to customers requirement. We can provide the pedometer for shoes, table class pedometer and bracelet pedometer wearing on wrist, pedometer wearing on waist and pedometer putting inside the pocket. Pls indicate clearly when purchasing. II. Features High precision 3D pedometer algorithm Low sleep current Ultra-small size IIC interface III.

Working mode 1) Normal work When detected step action, module will enter normal working mode, users can read the step value by I2C interface. The I2C communication protocol is as below DATAO: step lower byte DATA1: step high byte DATA2= DATA0 + DATA1 DATA3= DATA2 When the steps overflow, it count from 0 The steps will be cleared when DATA3 is read. Note: All the bytes are hexadecimal 2) Sleep ing mode The chipset will enter normal working mode when step action is detected, and enter sleeping mode if no step action is detected for 20s. In sleep mode the G sensor doesnt work, the MCU will enter deep sleeping mode and the whole module is in low power consumption. TEL:0755-61596687 FAX:0755-27838582 www.nicerf.com www.nicerf.cn 2 4
