The strings are typically 100-150 characters long, data dependent of course. The API uses a single http “GET” request for this purpose. This free service supports up to 8 updates at a time. Saving the data somewhere independent of the hardware that first acquired the information makes more sense. This approach, if relied solely for data storage, keeps your system isolated, Not exactly an IoT solution. You cannot get access to the data unless the Arduino is running, and you are located in the same area as the system. But there is a shortcoming with this approach… That would protect the data from system crashes. One option is to add an SD card or some similar storage device to your Arduino circuit. So here it is…Īfter playing with an Arduino for a while, collecting sensor data, the logical next step is to add a method of saving this data for future consumption. And the solution could save you precious time. I suspect many others have also encountered the same issue. I recently came across a challenge while working with an Arduino serial interface.
