NXP-based high-precision smart watch pedometer reference design

Program Description:

The smart bracelet is a wearable smart device. Through this bracelet, users can record real-time data such as exercise, sleep, and some diets in daily life, and synchronize these data with mobile phones, tablets, and iPod touches to guide healthy living through data. Mainly through the NXP's MMA9555 accelerometer for the CSR1010 platform, the MMA9555's performance and accuracy are the choice of most engineers.

The main function:

The MMA9555 low-power MMA9555L intelligent motion sensing pedometer integrates 3-axis MEMS accelerometers, signal conditioning, data conversion and 32-bit microcontrollers for portable mobile consumer electronics;

core advantages:

      1. Target applications include pedometers, wearables, smart watches, bracelets, sleep monitoring, smart headsets and health monitoring

2. Integrated sensor initialization, calibration, data compensation and calculation functions

3. Provide precise pedometer function and 6-directional directional monitoring

4, can provide highly accurate step count, step size measurement, calorie consumption and activity type detection

5, including automatic sleep / automatic wake-up function
