Detail about Heartbeat Sensor Detector Module 

This module can store 15 pieces of voice instruction. Those 15 pieces are divided into 3 groups, with 5 in one group. First we should record the voice instructions group by group. After that, we should import one group by serial command before it could recognize the 5 voice instructions within that group. If we need to implement instructions in other groups, we should import the group first. This module is speaker-dependent. If your friend speaks the voice instruction instead of you, it may not identify the instruction. We all know that there is a kind of module which can control the light on and off. You make a sound, the light turns on. Then after a while it turns off. This is not voice recognition. We may call it Sound Control. Voice recognition is something that knows exactly what you were saying. We've been thinking about a module which helps to control other devices by voice and it will not cost too much. Finally we designed this module. Well, what can this module do? It can recognize as much as 15 voice instruction, which is suitable for most cases involving voice control.
