Add arduino read data from sensors

I have a gps tracker that have a 1wire connection with 3 temp sensors (DS18B20).
I need to know if it´s possible add a arduino to read the data of that sensors using the existing 1wire connection?
In resume, it´s possible using the same connection 1wire to the gps tracker and to the arduino?


Did you write the code for the GPS tracker? If so, please post it.

Please explain what you’re trying to achieve. Why do you think that you need an (another?) Arduino? Can’t you connect the sensors directly to the (other?) Arduino?

Hi, @davids2006
Welcome to the forum.

Please read the post at the start of any forum , entitled “How to use this Forum”.

To add code please click this link;

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

So do you already have an Arduino that is connected to the GPS and 3 DS18B20 sensors?
Your first line is not very informative.
What GPS?
What Arduino if you have one with the GPS?

Thanks… Tom… :grinning: :+1: :coffee: :australia:

Sorry for not explain well.

I have a gps tracker ( queclink GV65 (GV65 | Queclink)) that have connected 3 sensors by 1wire.
This work fine ( i can see the temperatures ).
I can’t “talk” with the gps tracker by uart or other protocol because is a closed software.

Now I need show in 1 lcd the temperature of that sensors.
I need to know if it´s possible add a arduino in the middle to read the temperatures and dont interfere in gps tracker reader.
I make a schematic to understand the original schematic is from [Digital thermometer using Arduino and DS18B20 sensor (]
In resume I want make a sniffer to the 1-wire bus and show the data in the lcd.
