IOT Network Proposal for the Identification, Monitoring and Location of Crocodiles in the Estuary of Puerto Vallarta, Jalisco, Mexico

Abstract

In the city of Puerto Vallarta, in Mexico, there are crocodiles, distributed in the BahÃa de Banderas area, between the states of Nayarit and Jalisco. Man invaded their habitat, forcing them to look for those spaces they naturally occupied, generating confrontations. This work describes and gives the background of the problem, as well as a possible way to mitigate the situation, the use of IOT technology is proposed to monitor the location of each crocodile and the definition of risk zones to warn of possible dangerous situations. Therefore, the design proposal of a network of wireless sensors for the monitoring of crocodiles that are found in the area of the estuary and the Marina, which is an area surrounded by commercial and residential areas, is carried out. The use of a LORA network is proposed, since the coverage of the Coast, mangrove swamp and Marina is around 8 km. Also, a star topology with a single hub and a gateway node was chosen to send the data to a server. A NoSQL database service such as Firebase and data visualization software using React Native are proposed. The data of interest for the project will only be the latitude and longitude provided by the GPS and that will be decoded through an mkr 1300 development card. With the application of the project it is possible to know the behavior of the reptiles, act quickly in case that the crocodiles are outside their natural area and notify Civil Protection.
