Design and Implementation of RemoteControlled Fan Regulator

[摘要] This paper presents the design and implementation of an infrared remote controlled ac fan regulator. The regulator consists of IR sensor, monostable multivibrator, decade counter, transformer, comparator, opto-isolator and TRIAC. The user will be able to operate the regulator with any remote control used for TV, VCR, Air-Conditioner, DVD player etc. The remote transmits a beam of light and this light is picked and decoded by the receiver unit. The receiver only activates when it receives the beam of light. Every time when the button is pressed, the speed of the fan is increased smoothly up to ten different speed levels. The fan regulator has been simulated and experimentally tested. It is found that the system works satisfactorily and the experimental results are almost same.
