Elephant Intrusion Detection, Deterrence and Warning System (“Tusker Alert”)

Abstract

The Human-Elephant Conflict (HEC) is a serious socio-economic problem in Sri Lanka. Many methods including traditional electric fence systems to novel technological approaches are being used to minimize the HEC. Each method has its limitations, complications, and disadvantages. To prevent and overcome them, a wireless sensor network-based detection system combined with a warning system, and an artificial bee sound-based deterrence system was proposed in this research. With the help of PIR and infrared sensors, intrusion can be detected, while by emitting recorded bee sound, deterrence can be accomplished. By combining those two aspects with a communication network, a warning system was developed to alarm relevant authorities such as the wildlife department, railway authority, and police stations through SMS alert system, mobile app, and warning light system while a database is also being updated regarding the intrusions which can be used for further analysis and predictions. Application of the system covers wider aspects of detecting and warning of elephant intrusions such as on village forest boundaries, rail tracks, and on roadsides (possibly on expressways) with a tested and proven result of 92% detection rate from controlled environment testing.
