## Overview

The KEMO Ultrasonic Signal Generator Module is a compact, energy-efficient device operating on 12-15V DC that emits adjustable ultrasonic frequencies between 8kHz and 40kHz. Designed for multi-speaker setups, it effectively repels a wide range of pests including rodents, insects, and birds. Its durable, fully potted enclosure and intuitive rotary switch make it a reliable and versatile solution for professional-grade pest control in various environments.

## Description

Through ultrasonThrough ultrasonic sounds it is possible to scare away animals and insects like rats, mice, martens, wild rabbits, mosquitoes. If mounted on the car, roe will be put to rout (decreased danger of accidents). Connection of a piezo-treble loudspeaker to the module is an ideal way to scare away destructive animals out of your pantry, kitchen, storehouses, garden, etc. Also can be used as dog whistle. Even some birds species will be scared out of your fruit trees.Item SpecificsOperating voltage: 12 - 15 V/DCCurrent consumption: <50 mALoudspeaker output: up to 5 piezo loudspeakersAudio frequency: adjustable ~8 - 40 kHz (± 20%)Size: 60 x 45 x 29 mm (without fastening straps)A speaker & power supply are required for unit to function properly. Indicator light will not turn on without a speaker and power supply wired to the unit.

## Features

- Compact circuit is housed in a fully potted plastic enclosure and can be powered from any 12~15VDC power supply

## Questions & Answers

**Q: Someone mentioned the frequency fluctuates. Can you lock in a frequency or does it always fluctuate?**
A: My unit does "waver" at about 2 Hz around the set center frequency. When in the audible region it sounds like a sound effect in an old TV show. The "wavering" is definitely an intentional design feature, not a problem with the circuitry. I watched the output on an oscilloscope and the wavering continues even as the frequency moves to the highest end of the frequency range. For any use other than a pure signal generator, like trying to drive away critters, the wavering is probably a good design feature.

**Q: If I use this device + piezo loudspeaker + bullhorn will I be able to get the desired effect on a dog about 150-200 ft away?**
A: It works good on some dogs at that range, but others can be within 50 and ignore it.  We had 3 dogs next to us and 2 of them never noticed and the 3rd one would stop barking and run for the house.  He would head to the house when he was at least 200 feet away, he soon became a non barking dog.

**Q: Any idea what AC power adapter to power this unit? thanks**
A: i used  12v 1A unit..

**Q: Can this run on batteries? Or only DC power plug?**
A: Batteries such as AA or AAA or similar chemical batteries are DC.  The device does not come with a battery compartment. I guess if you attached a battery the device would work.
