ECO – Data Acquisition System

The 3S EnvironmentalCheckerOutdoor (ECO) is a versatile sensor platform that was primarily developed for the use in complex application scenarios for monitoring ambient air. Temperature spectroscopic analysis of gas mixtures – the 3S core competency – is modularly complemented by a variety of specific sensor principles to achieve a comprehensive picture of the situation. This modularity makes the ECO a universal multi gas detection system for all possible applications of continuous measurement:

  • Air quality monitoring at emission and impact site
  • Monitoring of biogenic emissions, for example in animal husbandry and plant breeding
  • Monitoring of fermentation processes
  • Monitoring of chemical production processes
  • Effectiveness control of gas cleaning systems
  • and more

The multi gas sensor system ECO can be parameterized flexibly and is perfectly suited for continuous monitoring of all kinds of processes or environmental situations.

Due to its rugged design and its flexible energy management (mains operation, battery operation, vehicle electrical system), the ECO is especially suited for the use in outdoor areas and harsh environments.

For use in other application environments, a compact, portable plastic housing is available.

The system features several measuring channels for sampling and can be equipped with various sensors or sensor principles. Extension modules allow for electrical connection of actuators and input devices.

The data are aggregated in a flexible format that can be easily analyzed (HDF5), transferred to a backend server via mobile communication, WLAN, or ethernet, and can be processed appropriately afterwards. Local data storage in .h5 format on a USB stick is also possible.
