Technologies help to improve our living enviroments and let us working effectively and efficiently. We are trying to introduce the-state-of-art technologies to our customers in this pages. Human Presence Detection:Vibration sensor is used to detect the heart beats of human in the enclosed area.The analyze algorithm is used to sort out the signals receiving from the sensors and to judge if there is any human existed in the enclosed area.
