Dengue, a disease carries by mosquitoes, is becoming more fatal especially in tropical countries. PenyuBuzz has been developed with the main purpose to become an alternative for dangerous insects repellent. PenyuBuzz is currently purely based on theoretical study with no scientific evidence. Even though it is not 100% effective, gradual and continuous researches will be conducted for improved effectiveness. Researchers are highly welcome to feed us with more info on subject matter for us to develop better solution. PenyuBuzz will generate ultrasonic sound which cannot be heard by normal human which is normally between the range of 16 to 20 KHz, depending on age and other factor. Whilst mosquitoes and other insects have the audible range of ultrasonic sound, PenyuBuzz will generate random ultrasound to get rid of them.
