MDL-700™ is a programmable data logger with a Linux* operating system.
MDL-700 is purpose-built by Dyacon engineers for environmental and site monitoring applications. System architecture is tuned to the unique needs of remote data collection and control, low power, PC-like I/O, and expandable sensor input and control options.
The open-source operating system allows software developers to utilize familiar programming tools and data interfaces in order to create a custom solution in a short time. Programmers can build applications on their desktop or directly on MDL using Python, C, or C++.
The expandability and programmability of MDL data logger make for an exceptionally versatile system that can be adapted to a broad range of applications. Data connectivity via FTP, MQTT, email, web server, and more are only limited by the needs of the application and creativity of the programmer.
Those migrating from hobby boards will appreciate the integrated system, including display, hardened electronics, and industrial connectors.

Unsure of your needs?
Let us help!
MDL-700™ uses a solid aluminum base with provisions for both wall and DIN rail mounting.
Ethernet uses standard 8-pin modular connector. Standard Type-A and B connectors are used for USB host and device connections.
Environmental data logger applications imply unique input requirements for measurement needs. MDL-700 accommodates a diversity of applications with modular construction. Researchers and sophisticated industrial users can add I/O boards to the base module. Expansion boards may be attached to the left or right sides.
Left side board include power input and control output options.
Right side expansion modules add sensor inputs and low-current control output.
MDL-700 Web Interface
The MDL-700 performs measurement and data logging operations using highly configurable, open source, Python software: DataBear (github.com/chrisrycx/databear). DataBear is available to all users, but requires a significant level of technical knowledge to implement. To make the Linux data logger approachable to a broader range of users, Dyacon “MDL Web Interface” (to be released Q1 2021) is a graphic, user-friendly interface for logger configuration.
The Web Interface (WI) comes pre-installed and enabled on all MDL-700s. To use the WI, simply connect a laptop directly to the MDL using an Ethernet cable. Once the MDL is on the network, a browser is used to connect to the MDL. The initial login page enables administrators to control user access to logger settings.
Once logged in, the WI provides full control over measurement and logging via the ‘Configuration’ pages. This includes adding and removing sensors, changing measurement intervals, and also changing specific measurements to be logged. The Acquisition page displays current measurements and plots the logged data. Logged data can be downloaded to a CSV on demand.
MDL web interface continues to expand. Please stay in touch to watch the progress.
