ARCH GPRS With Xively

IOT Architecture

  • Xively is an on-line database service allowing developers to connect sensor-derived data (e.g. energy and environment data from objects, devices & buildings) to the Web and to build their own applications based on that data,to know more, visit https://xively.com/
  • Here, we use ARCH GPRS to post our sensor data(temperature/light/humidity etc.) to Xively.

ARCH GPRS Introduction

ARCH GPRS

  • Arch GPRS is a wireless network module based on EG-10, it can achive remote data colletion function to communicate with outside world by GPRS network.
  • Arch GPRS has standard Arduino interface and Grove connectors. It’s convenient to connect existing Shields and Grove products to Arch GPRS.
  • You can use the solar panel to charge for battery, and own to its low-power design, so Arch GPRS can work normally in outdoor.
  • For more information, please visit http://www.seeedstudio.com/depot/arch-gprs-p-1657.html?cPath=6_11

Code

  • Description: this demo is used as posting value of sound sensor to Xively every 10 seconds.
  • Attention: you need to replace the PHONE_NUMBER/FEED_ID/SENSOR_ID/XIVELY_KEY with yours.
