Open Hive RFM69 sensor node#

Tip

Please continue reading this document on our documentation space, all inline links will be working there.

Introduction#

The Open Hive Box RFM69 is a sensor node transmitting data using radio link communication. Telemetry data is serialized using CSV and transmitted to the receiver node Open Hive Arduino Yún gateway or Open Hive JeeLink radio gateway.

The most recent firmware version is available at rfm69-node.ino.
