Hi all,

I have MPL3115A2 sensor for temperature and pressure and it is connected with raspberry pi . I want to use a node-red to get data from this sensor. Is there any way to do that?

I will appreciate any help

check [flows.nodered.org](http://flows.nodered.org) for a list of most nodes available. There are some for specific sensors and some for i2c

Thanks  
I found " node-red-contrib-i2c" node, but I can't find any example or document about it. How can we configure it? what is the type of address? etc. I tried many things and it didn't work
