The project "Development of a datalogger on an Arduino platform" was started by Lucas Barbosa Rocha (UFRN), an undergraduate electrical engineering student, under the guidance of Senior Technologist Jo?o Gualberto de Cerqueira J?nior (CRN/INPE). The datalogger, developed in the laboratory, will store pre-defined environmental parameters from the monitoring areas. The scope of this project ranges from the hardware and software design of the sensors to the construction of a PCB prototype, with laboratory and field tests.
