The PCB provides a small prototyping area where any THT component test circuits can be mounted to test specific applications. four LEDs, plus two general-purpose buttons.buzzer for acoustic signals depending on operating conditions.two independent relays for the management of any loads.jumper to select connection of ZCD line to Arduino board connection to I/O A12 for management through PCINT20 peripheral or to I/O 20 through INT1 peripheral.TA and TV connection to the FT1346M board (TA and TV are mounted on an auxiliary board).ZCD (Zero Cross Detection) line connection to FT1346M board (I/O A12 or 20).MCLR and RESET control lines connection to FT1346M board (I/O 46 and 45).Data connection to the FT1346M board via UART 3 hardware interface (I/O 14 and 15).The hardware we developed has the following features: In the project described in these pages, we will use the Arduino Mega 2560 (or Fishino Mega), which will “run” a sketch integrating the management library of the MCP39F511 and dedicated hardware for the interconnection of the FT1346M board. This will be combined with the new GSM Shield to add a mobile data connection and send the acquired measurements to a remote server.
That’s why, using our “energy meter” board FT1346M (based on MCP39F511 and presented in the previous post) we will propose a series of articles in which we are going to develop a measurement system based, first, on Arduino boards and then on other architectures. The electrical measurements made, grouped in a database and then shown in graphical form, allow you to assess the consumption trend over time. Monitoring the electricity consumption of your home or business is an increasingly topical issue. The read data are processed from the sketch and then sends to the PC via Xbee module.It monitors electricity consumption and sends the detected data to the cloud through the GSM cellular network it is based on an Arduino Mega equipped with GSM Shield and an absorption detector board. This potentiometer has the task to adjust the sensitivity threshold. The LED blinking causes the voltage drop down and this value is read by Arduino and compared with the voltage acquired by the potentiometer connected in the channel A0.
