Supported Protocols

OpenSensorHub (OSH) has built-in support (via add-ons) for various procotols that sensor adapters and other modules can be built onto.

Network Protocols

Hardware protocols modules are mainly used within a sensor adapter and provide the heavy lifting to support a particular type of hardware communication:

• Serial / RS232
• USB Serial
• Bluetooth Serial
• Bluetooth LE + GATT
• WiFi / Ethernet with ZeroConf Discovery
• Zwave (via USB adapter)

Coming soon:

• Zigbee
• SigFox (via serial modem)
• LoRaWAN

You'll find the code supporting these different protocols in the 'comm' subfolder of the osh-addons repository (opens new window).

IoT Protocols

IoT protocols provide more advanced Plug & Play capabilities as well as communication with other IoT systems such as the AWS IoT cloud platform:

• MQTT

Coming soon:

• BLE "Generic Measurement Profile"
• Adafruit Unified Sensor Driver
• CoAP

Web Protocols

We also support OGC web services and RESTFul interfaces that can be used to access, task and discover sensors connected to a Sensor Hub:

• Sensor Observation Service (SOS + SOS-T)
• Sensor Planning Service (SPS)
• Sensor Web API
• Sensor Things API
• P2P Discovery Layer (coming soon)
