Several pre-made arduino projects need to be collected to one main project. The collected data from different components will be transmitted to a Siemens PLC. All components have pre-made and tested software, see uploads, but need to be in one project. Some conversions and buffering is missing. That's the difficult part for me.
It will be running on a Arduino Mega with Ethernet Shield.
Component 1: 2 RFID sensors connected on SPI bus
Component 2: Smart power meter data
Component 3: Analog Lightsensor
Component 4: Temperature and Humidity (DHT11)
Interfacing: By use of the Settimino library, all collected data will be transferred to a Siemens S7-1200 PLC.
