Summary of ULTRASONIC CAT & DOG REPELLER CIRCUIT PIC16F627

This article shares resources for an ultrasonic cat and dog repeller project using a PIC16F627 microcontroller. It includes ASM source, HEX, Eagle PCB and board files. The device emits varying ultrasonic frequencies via a piezo driven by four power transistors, with selectable fast or slow frequency transitions and an optional key (switch) for operation. When programming the PIC16F627, the internal oscillator fuse must be selected.

Parts used in the Ultrasonic Cat & Dog Repeller Circuit:

  • PIC16F627 microcontroller
  • Piezo transducer
  • Four power transistors
  • Push button or key (operation switch)
  • PCB (Eagle board files provided)
  • Power supply (battery or DC source)
  • Supporting passive components (resistors, capacitors)
  • Connector pins and wiring

NOTE: When programming the PIC16F627 internal oscillator fuse should be selected.

In order to prevent pests from entering the inside of the house, etc. According to them we wanted to make a very noisy. Trial tremendously effective on dogs and cats in my circuit, I saw, she seemed. We can not experiment on mice, we did not found a mouse 🙂 but the project did not prepare them thinking. All of these animals they like, changing values ​​in all available frequency ultrasonic sound. This circuit, with four power transistors to drive the piezo randomly in different ways all these frequencies can give. Operation can also intrigues with the key. Fast or slow frequency crossover transitions can be achieved. http://endtas.com/robot/modules.php?name=News&new_topic=6 Prepared by: Ozkal Özsoy
