Characterization of an RFID reader in saltwater

Research in various natural ecosystems has had a greater interest in recent years, for an evaluation, detection, and measurement of the changes that occur between the ecosystem and the species that inhabit it, all with the aim of knowing if these changes are consequences natural or the result of deliberate or unintentional human interventions. For this reason, different tools have begun to be used to carry out a detailed analysis of some of these places and, therefore, of certain species. An example of the implementation of these tools is the use of radio frequency identification systems (RFID) for species monitoring, which has been used to control the number of species in a specific area. However, the RFID systems that are implemented in these studies are usually placed in fixed places outdoors, also, no data has been found on the network on a detailed analysis of the behavior of RFID readers when submerged in water. Therefore, the interest of this research is to perform an analysis of the RFID low-frequency readers in two different test scenarios, with the aim of being able to implement them for the monitoring of marine species, which are affected using frequencies. higher than 150kHz that cause damage to their nervous tissues and temporary loss of hearing. For this research, two test scenarios are proposed, to make a comparison between both scenarios and observe the feasibility of being able to use RFID readers and passive tags in environments where they must be submerged in water.
