These posting point out collecting data. Also, this unwieldy mass of data needs to be logged, processed, stored and displayed in a reasonable way for it to be usable. Then, show how to create a feed and upload data reading from sensor an to Cosm via an Arduino Ethernet Shield.
All of the devices around us are starting to become data collection points. Every minute of every day many data points are generated. This unwieldy mass of data needs to be logged, processed, stored and displayed in a reasonable way for it to be usable. The question becomes how to do this. One solution for the DIY community is Cosm (formerly Pachub) that allows us to do just that for free. In this article I’ll show you how to setup an account, create a feed and upload temperature readings from an I2C temperature sensor to Cosm via an Arduino Ethernet Shield.
Arduino and Ethernet Shield or Arduino Ethernet
Breadboard and jumper wires
tmp100 (or other I2C temperature sensor) on a breakout board
Setup a Cosm Account
Cosm site is changed to Xively.
If you don’t already have one the first thing you need to do is setup a Cosm Account
The W5500 Ethernet mainboard is the newest member of the DFRobot Ethernet family. It Is a microcontroller based on the ATmega32u4 and W5500 Ethernet chip with the same footprint as an Arduino Leonardo board, as well as being compatible with most Arduino shields and sensors, making it suitable for many kinds of IOT applications. The W5500 chip is a hardwired TCP/IP embedded Ethernet chip that provides easy internet connection for embedded systems. The board has the TCP/IP stack, 10/1000 ethernet MAC and PHY embedded, allowing internet connectivity in the users application using just the board and nothing else. The W5500 Ethernet mainboard uses a high-efficiency SPI protocol which supports a speed of 80MHZ for high speed network communication. In order to reduce power consumption it also includes WOL (wake on LAN) and power down modes. The board can be powered using a regular VIN, or POE as the power supply. It also integrates a power regulation chip that allows it to work under a complex environment.
