The development of Rat Repellent system is to ensure the frequency of Ultrasonic sensor to cover at all houses but it is difficult to do that because the frequency cannot through the wall. So, the solution for this problem is to do a different unit. Small unit is to place at all area that the human detect the habit of rat or the area that always have a rat. By doing the small unit the house is protected by the ultrasonic repellent. The Ultrasonic repellent is not on all the time but it only on when the motion detector detect the rat. The other problem is how to make the main unit function as a wifi to send the signal and receive signal between small units. So, the solution is to use Radio frequency (RF) 315MHz as the transmitter and receiver. Next is how to communicate between the small unit and the main unit in order to make the process function as a wifi. Lastly is the small unit needed to have a long lasting battery because the user will not to charge the small unit every day. It is because it will burden the user to charge the small unit every day and it gives the badness outlook to user to buy this product.
Scope of project
The scope of this project is to develop the current electronic repellent and evaluate the behavior of the rats by using ultrasonic rats repelled.
