How Smart MailBox Perform

  • Post author:

One year prior, I planned a Smart Mailbox utilizing the Arduino MKRFOX 1200 board. The board interfaces with the cloud through the SigFox organization. The Smart Mailbox was built at the Mouser Electronics Germany branch in Munich, and we have been trying it for as long as year. In the accompanying, we’ll survey the exhibition of the board over the earlier year.

Foundation on the Smart Mailbox Project

SigFox permits clients to send up to 140 messages each day, with each conveying a payload of 12B. In my application, I didn’t have to send the entire payload. So to save some battery power, I decreased the payload to just 1B. This 1B contained hexadecimal of the excess battery rate. The battery rate is determined utilizing the condition beneath:

This computation is a best guess of the battery’s condition of charge. In a perfect world, a battery charging circuit, for example, this is expected to work out the battery limit, which then, at that point, can be utilized to ascertain an exact condition of charge. In light of Arduino’s site, in the event that you supply the MKRFOX 1200 board utilizing two AA or AAA batteries (1.5V each), the block ought to work for to a half year with ordinary use.

Update on the Smart Mailbox Project

Our shrewd letter drop has been sending three messages each day by and large. SigFox offers the client the choice to take out got information with a constraint of 50,000 passages. The information is saved in a CSV design, as shown in a diagram (Figure 1). The diagram shows the shockingly great power utilization of the MKRFOX 1200 board. The blue line addresses the battery condition of charge, and the red line is a trendline to improve on the variances of the battery level changes.

The batteries were completely energized when I began building the venture, however you can see the diagram starting at a 80 percent condition of charge in the outline. This condition of charge was the point at which the board was mounted on the letter box and was working ordinarily. The 20% battery rate was lost in light of testing during the structure interaction. A significant highlight consider is that the MKRFOX 1200 is customized to go into rest mode after the instatement cycle and possibly wake from the rest mode when set off by the sensor. By this, the Arduino MKRFOX 1200 is working in low-power mode more often than not. Figure 1 shows that the bend is basically the same as a commonplace 1.5V AA-battery release chart. The supposition that will be that our shrewd letter drop is arriving at the end voltage very soon.

SigFox Subscription Renewal

The Arduino MKR FOX 1200 incorporates a one-year free membership to the Sigfox organization. In the accompanying segment, we’ll show steps on how restore the membership.

  • Explore to
  • Login utilizing a similar SigFox ID you use for the Sigfox Backend.
  • After you sign in, click on Buy Connectivity.
  • Pick your favored arrangement and continue to the installment.
  • After you finished the installment, explore to the SigFox Backend.
  • Click on Device Type.

In total agreement, click on your DevKit and tap on Edit.
Glue the new agreement number in the agreements field, and a rundown will spring up where you affirm your choice.

Click on OK at the lower part of the page, and your Arduino MKRFOX1200 should be back in activity.

In general, the Ardunio MKRFOX1200 has been working very well as far as power utilization and unwavering quality. The SigFox network inclusion is additionally brilliant in my space, however this relies upon which region you need to convey your application.
