Based on today"s network technology and the development of smart home status, this paper introduces a intelligent human tracking fan which based on heat release electric infrared sensor.MSP430F149 is selected as the controller in the design.The body motion and position information are detected by the human motion detection module which is composed of 5 HC-SR501 pyroelectric infrared sensors.Adjusting the fan head tracking human movement which is accomplished by controlling the motors, so as to achieve the two-dimensional direction of human tracking.The whole system has strong practicability, high integration, low cost, light volume, high cost performance and wide application prospect.
