Plačilo ob prevzemu
I need a PCB board which is sending SMS to a telephone.
This SMS should be the message of the Modbus alarm code
It should also be sent a SMS when power is off.
The number on which should be sent,
should be configured about a SMS sent to the SIM of the PCB.
At first I need 5 prototypes and then I need 1000 piece for first order.
Price per piece for prototype should be under 50$
Price per piece for first big order should be under 10$
Price for parts are separated from the project price...
It should be powered by 230V
