Collecting sensor data from geographically-dispersed, low-powered data loggers is a problem. The loggers can record many kilobytes of data, which must be periodically gathered. Sending “collectors” into the field to connect to each logger one-at-a-time to upload the data is time-consuming, cellular radio requires lots of power and building a mesh radio infrastructure to “route” the data is expensive and often impractical.

We asked the question “would it be possible to gather sensor-logger data while driving by the remote sites without stopping?” Current radio protocol choices were not designed for this scenario. Low-energy radio protocols such as BLE transfer data slowly. Wi-Fi uses a lot of power and may take seconds just to establish the connection.

This talk describes a simple radio protocol, which operates at low power while waiting for a radio connection, yet is able to change modes and transfer bulk data at high rates. The protocol is open-source and available for down-load from GitHub.
