Best Kit / Board / Controller for Small Industry Project

[Satya Prakash Prasad 0]

I have a Industrial Project requirement to build up a device having functionality: 1. Dispense Liquid in multiple of liters 2. Store Data (ID Number probably a storage device) 3. Send Data to Web Server 4. Be placed in remote Village (device to be placed under scorching sun) 5. Sensors - flow, level, solenoid valve and a couple of more 6. A Graphical Dashboard 7. RFID authentication (offline - based upon a logic) 8. Buzzer and maybe a couple of more. Can PLC help me in developing this Industry project having above functionality? How much voltage of power supply would it require - as we tend to operate using a battery (5 volts DC?) - we need to keep re-charging the battery or be recharged by a mobile phone via USB connector? The other alternative we were thinking of is of Arduion Mega Board or AVR 32 UC3 - but PLC is already proven for usage in Indutry Projects. Since I am new to PLC development - please let me know how easy / difficult it would be to start coding using PLC?

Most PLCs use 24 volts DC or 120/240 volts AC power. Likewise most industrial sensors are 24 volts DC. If power is a problem, then you'll probably want to go with the Arduino. I would consider PLCs to be pretty easy to program, especially if you come from a programming background. If you can program an Arduino, then you should be fine. There will be some getting used to the ladder logic style that most of them use, but it's a fairly visual language, so even that shouldn't be too bad.
