Aiming at the problem of low automatic control level for the existing bladeless fan, a design scheme of the bladeless fan control system based on multisensors is presented. The system uses the pyroelectric sensor HCSR501 and the infrared sensor GP2Y0A02YK0F to detect the body position and the distance between human body and bladeless fan respectively, and applies PWM technology to control the wind speed of the bladeless fan. Experiments show that this system can automatically adjust the blowing angle of bladeless fan in accordance with the body position changes, and can control the wind velocity of bladeless fan according to the distance between human body and bladeless fan. Further, the system can provide constant blowing speed and good blowing feeling for the user within a certain range, and can better realize the intelligent control.
