The Arduino MKR FOX 1200 board provides a practical and cost-effective solution to add Sigfox connectivity to projects requiring low power. This open-source board can be connected to Arduino Create for programming, and to the existing Sigfox infrastructure with its broad Europe-wide coverage for collecting data. Sigfox infrastructure runs 24/7 without you needing to do anything to maintain it, and you can always check its status here.
The MKR FOX 1200, gives you a great out-of-the-box experience when building IoT projects of any size: from the single sensor monitoring temperature in your home to an industrial deployment covering the whole of an outdoor factory. The board's main processor is a low power Arm® Cortex®-M0+ 32-bit SAMD21, like in the other boards within the Arduino MKR family. The Sigfox connectivity is performed with a module from Microchip®, the Smart RF ATA8520, a low power chipset operating in the 868 MHz range. No extra crypto chip is needed in this case, since the Sigfox network offers its own end-to-end security.
These features make it a great IoT node and building block for low power wide area IoT devices within the Sigfox infrastructure.
Sigfox is a Low Power Wide Area Network (LPWAN) technology specially designed for the IoT (Internet of Things) devices. Devices and sensors which are connected with Sigfox, consume very little power and can function over large distances when compared with Wi-Fi and Bluetooth connection protocols which consume a lot more power and work best in short range. Also, it is an inexpensive and reliable solution.
Sigfox technology leverages the use of antennas that are installed on towers in an area and obtains data from devices and sensors around it such as parking sensors and temperature sensors. These transmissions use Band frequencies such as 915 MHz (US) or 868 MHz (Europe).
SigFox wireless systems send very small amounts of data (12 bytes) very slowly (300 baud) using standard radio transmission methods (phase-shift keying (DBPSK) in the uplink and frequency-shift keying (GFSK) in the downlink). The long range is accomplished as a result of very long and very slow messages.
The process of a Sigfox application can be broken down into the following four steps:
Every MKR FOX 1200 comes with a free one-year subscription to Sigfox's data plan, useful for testing the Sigfox network. Please check the plan’s conditions in terms of messages per day at the Sigfox website.
When it comes to coverage, Sigfox covers a large percentage of the European soil. Check this page at the Sigfox website to see whether your planned area of application is covered.
The USB port can be used to supply power (5V) to the board. It has a screw connector to attach a 3V battery pack. The board consumes so little that it runs on two 1.5V batteries type AA or AAA for a really long time.
The Arduino MKR FOX 1200 requires a GSM antenna to be attached to the board with the micro UFL connector; please make sure that the antenna is compatible with the frequencies in the SigFox's range (868 Mhz).
