Uploads to SensorCloud are typically dominated by the data content, with minor additional overhead for secure communications. One simple method to estimate upload bandwidth is to multiply the number of samples to be uploaded by 12 bytes. Each uploaded sample contains an 8 byte field for the timestamp, and a 4 byte field for the value. Example: If you have three nodes with one channel active all sampling at 32 Hz, your effective upload rate would be 96 samples per second. Multiplying by 12 bytes per sample, this amounts to 1,152 bytes per second. This amounts to 2,985,984,000 bytes over the course of a month, or approximately 2.78 GB.
