[SOLVED] 1- Wire (One Wire) Sensor and Powerline

Hi to everyone!

I would like to monitor my basement temperature using the famous 1-wire DS18b20 sensor. I cannot put any cable in my house, so i thought to use the powerline technology.

This is my idea:

Arduino <--uart--> Powerline Modem <---> Powerline Modem <--uart-->DS2480B (Serial to 1-Wire Line Driver) <--1-Wire --> DS18B20

What do you think about it? Is that possible?

I didn't choose the powerline IC modem yet, there are a lot on the market, maybe the ST ST7540 with 4800 baudrate could be good.

The DS2480B (pratically the 1-wire bridge) needs 9600 baudrate, to ensure the reset for the 1-wire. St7540's got progammable baud rate for serial interface,but the trasfer after the modulation is 4800 Baud.. could this be a problem?

Does the modem buffer data and then transmit at the baudrate programmed? I can't find any answer to this question..

Thank you so much for the attention.. any help would be appreciated.

P.s. Hope this is the right section for this thread..

When using power line modems you know that nodes must be on same phase.

People usually have three phase in house/buildings and that can be problem, or you can use three modems separately.

Did you consider using some RF tech for data transfer ?

Speed (bandwidth) and latency (delays) will be quite a challenge
