GSM based on off
-- circuit and PCB layout design (PCB layout ready for fabrication (Gerber file).
--Component
1) SIM800L (specified pins are keep accessible to microcontroller and user.)
2)ATMEGA328P SMD version (pro mini open source architecture with 8MHz and 3.3 V)
3) Voltage conflict management with lipo charging (power path management) (using this kind of IC MP2617)
4) Single phasing, reverse phasing, Unbalanced supply, Auto reset in such condition.( Reference circuit available)
5)two channel relay board and remaining I/O ports are kept outside with protection
6) Power supply(SMPS) for it (85-440V sustainable )
Block diagram and some specific requirement are discussed at finalising stage
Compleat payment released after the project is successfully tested.
The board with relays, ATmega328p and SIM900 is already developed. Take a look:

Hello,
I can do this work.
I develop concepts, design circuit, PCB and software for devices on Microchip and Atmel microcontrollers (C, C++, Arduino).
You can see some my works in my portfolio.
Regards,
Alexey
hello, i am mainly doing embedded designs and programs
i can do the work and do the code as you described
ie sense the signal from 3 phase sensing circut and control the 2 relays as you want according to SMS commands and send status messages
i can provide the source code for arduino
if you want i can give a cline mobile verification so that it work from only specified number
i can check the code working from side as per your requirement
you can contact on WhatsApp on (91) 9846105829
please contact if interested
