#include <ArduinoJson.h>

void setup() {
  Serial.begin(115200);

  StaticJsonBuffer<200> jsonBuffer;

  char json[] =
      "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";

  JsonObject& root = jsonBuffer.parseObject(json);

  if (!root.success()) {
    Serial.println("parseObject() failed");
    return;
  }

  Serial.println("reading: sensor");
  const char* sensor = root["sensor"];

  Serial.println("reading: time");
  long time = root["time"];

  Serial.println("reading: latitude");
  double latitude = root["data"][0];

  Serial.println("reading: longitude");
  double longitude = root["data"][1];

  Serial.println(sensor);
  Serial.println(time);
  Serial.println(latitude, 6);
  Serial.println(longitude, 6);
}

void loop() {
  // not used in this example
}

produces the following:

reading: sensor
reading: time
