Taking sensor's data from Arduino

How can i take sensor's data from Arduino with esp8266 and save it.
Simply use one of your favorite buses to communicate between Arduino and Pyboard, those are: SPI, I2C or UART
All differ in functionality and speed. So you need to have your requirements in mind.
And when you got the data it's your decision how to save it. On an ESP8266 sending the data over WiFi comes to mind first, maybe using HTTP Requests or MQTT. Of course that means you need to have a server (with a harddrive?) to receive the data and save it permanently.
The ESP8266 can also save the data byitself on a SD Card.
Without knowing your exact wishes and requirements we can't tell you what to do.
