SigFox and the IoT (4) Setting up a dashboard

摘要

In the previous instalments of this series we examined the basic Sigfox hardware for acquiring and transmitting measured data and the concepts underlying data transmission in the Sigfox network. Our measurements are now sitting in the Sigfox backend waiting to be picked up and processed further. A free web-based dashboard tool is available that lets the user create and operate a custom visualization and monitoring interface on any PC, laptop, tablet or smartphone. And, if suitably enabled, this dashboard can be called up and viewed by anyone (or just by any authorized user) over the Internet from anywhere in the world. The starting point for the developments described here is the Arduino sketch Sigfox-3_0.ino running on the MKR FOX 1200 board. If you select the fourth menu item ‘Send three readings’ then the three measured quantities (atmospheric pressure, air temperature, and light intensity as recorded by the LDR) will be continuously acquired, the results being shown on the ePaper display on the motherboard and output over the serial monitor to the Arduino IDE. When the button is pressed these readings will be automatically sent over the Sigfox network, received by the Sigfox backend, and stored. And from that point we can proceed to visualize the data on a dashboard.
