    For C# :

    JObject jResults = JObject.Parse("JsonString");
    String naming = jResults["sensors"]["naming "];
    String unit = jResults["sensors"]["unit "];
    

    For VB:

    Dim jResults As JObject = JObject.Parse("JsonString")
    Dim naming As [String] = jResults("sensors")("naming ")
    Dim unit As [String] = jResults("sensors")("unit ")
    

    You can achieve like this.
