title: [Development of the controller for alternative nebulizer].
abstract: OBJECTIVE
  To develop a nebulizer controller which can be used to control the ultrasonic nebulizer and spray atomizer which can optimize the working of the nebulizer in pulse way, in a purpose to save the medication and minimize the impact on the environment.
  
  
  METHODS
  Design the controller by using SCM to adjust the frequency and duty factor of the nebulizer pulse. The output pulse of the controller can drive a relay or a electromagnetic valve to control the pulse work of the two kind of nebulizer.
  
  
  RESULTS
  The controller can work in a pulse way, and patients can inhale in pace with the nebulizer.
  
  
  CONCLUSIONS
  The controller can save the medication by 50%, and reduce the impact on the environment by 50%.
