Devices & Protocols
Choose the hardware and measurement recipe that fit your field work.
In openJII, the hardware collects a reading and a protocol tells that hardware how to collect it. Choose both before field work so everyone in your experiment uses the same method.
Choose your route
- Use a MultispeQ for handheld, protocol-guided measurements taken by a person.
- Read Continuous sensors if you are bringing Ambyte data into openJII or connecting an Ambit or MiniPAR to the web workbook host. Ambyte is a gateway and ingestion family; Ambit and MiniPAR are distinct measurement-device families.
- Use Protocols to choose an existing measurement recipe, create one, or fork someone else's recipe before editing.
- Use Device commands to send a single raw
instruction (such as
helloorbattery) straight to a connected device. - Use Multi-device measurements when several connected devices should run one shared cell or be routed to family-specific protocol or command cells.
Beyond the named families, openJII can technically talk to any device that speaks a line-based serial protocol, whether over USB serial or Bluetooth Low Energy (BLE). The generic device family covers both transports; the named families add device-specific identification and drivers on top.
openJII uses device for handheld hardware that a person operates and sensor for autonomous hardware that sends observations over time. The interface also uses sensor family as the shared technical category for MultispeQ, Ambyte, Ambit, MiniPAR, and generic hardware. Despite that legacy field name, Ambyte is a gateway, not a sensor.
Prepare before leaving connectivity
- Attach a workbook to the experiment.
- Confirm that its protocol cells point to the intended protocols.
- Open the experiment in the mobile app while online so its pinned workbook version is cached.
- Connect the hardware and run a test measurement.
Then continue with Taking measurements in the field.
