Developing a data collection network by designing an iot-based sensor interface

In this research, it is aimed to create a data collection network by designing the internet supported sensor interface of the objects for the use of researchers in field studies. In this context, a main module is designed to handle Orange Pi Zero based data collection and server tasks. MongoDB database was used for data retention and NodeJS Express was preferred for service applications. The web interface has been formed for the user interface using AngularJS. Modbus, I2C and OneWire protocols are used to create a structure that allows the use of purposeful sensors and other modules. Modbus RTU A separate auxiliary module is designed to be used together with the main module using RS485 or I2C protocols. There are analog and digital ports and hx711 load cell amplifier on the designed auxiliary module. The software of the main module and auxiliary module have been prepared and the necessary configurations have been made. It was tested by connecting various sensors to the system realized and it was found that it was a structure that could be used in field studies by researchers.
