A Low Cost Effective Electronic System to Repel Monkeys that Damage Crop in the Dry Zone of Sri Lanka

A study was conducted to find a frequency range to repel monkeys. The first study looked at whether there was a good way to repel monkeys in the community. But there is no better way to get rid of monkeys in society. The only successful solution in society to chase away monkeys is to hunt them down using a gun. But the tester does not consider it a good solution. If not, a study was done to find a better way to do it. There is no range of frequency of the fear within the range of listening to monkeys. The study found that monkeys were frightened away by the sound of the AK 47 gun when they studied the sound of the guns given to them using a tda2003 amplifier.
