WHY
?
Sensor-agnostic.
Whether you’re using Stevens sensors or sensors from another manufacturer, they’re fully compatible. Field-installable connectors can be used to adapt existing sensors on an existing station.
...and many more!
Flexibility
Connect any type of sensor. The number of sensors that can be connected is limited only by the total power load.
Up to
10
SDI-12 sensors
Up to
4
Analog sensors
(0-2.5 V or 4-20 mA)
Up to
2
Pulse/counter sensors
Stevens-Connect
For logging, analysis, reporting, and storage of data from remote monitoring locations, Avo includes a one year subscription to Stevens-Connect (yearly plans available for purchase thereafter).
Our cloud-based data hub is incredibly powerful and incredibly intuitive. It’s used to configure your sensors’ logging and reporting settings. It stores and analyzes your data, notifies your smartphone when conditions are met, allows you to visually create custom calculations and “virtual sensors”, and it can receive and/or forward data from/to 3rd-party systems.
Avo is perfect for:
- Temporary sensor deployments where simplicity and quick assembly / disassembly are important.
- Linking existing sensors directly to the cloud.
- Any environmental monitoring application where minimizing complexity and maximizing reliability is important.

Unique Features
- Unified data interface experience: Sensor configuration, data storage, custom algebraic equations, custom data formats and forwarding, control, analysis, alarm notifications (email, SMS), reporting and actions all done with one simple cloud-based user interface.
- Easy configuration: Configure with any device connected to the Internet via the cloud-based Stevens-Connect. No custom programming or scripts required.
- Automated updates: Updates to firmware and cloud-based application can be automatic.
- Security: Three user access levels for configuration, data management interface and visualization. Data is saved on SD card and on the secured and redundant Amazon Cloud Services. Optional data encryption available.
- Connection verification: eTracker verifies connection with cell network and server connection before data is sent. If no connection is available or if data reception is not confirmed, data is saved and sent the next scheduled transmission.
- Data format flexibility: Optionally forward data in various formats for third party so ware platforms, like Aquarius or WISKI, and in other formats such as binary, pseudo-binary, SHEF, and more.
- Direct data access options: Third-party programs can access data using REST API or HTTP post.
3 steps to set up your station in minutes.
