- To decide new component to replaced
Procedure:
After been studied about RF Module and accelerometer, we decided to change to other better component. After been studied, RF Module contain many noise and quite hard to find coding, so we decided to change to Bluetooth. It can transmits data in range of 2.48Mhz so higher than RF Module.
Besides, we also decided to change sensor from accelerometer to Force Sensitive Resistance (FSR). This because some characteristics of the FSR is better than accelerometer. It have thin and flexible surface so it suitable with our project to put under shoe's insole. Hence, the price also affordable compared to accelerometer.
