7 essential functions that a data logger must offer in environmental technology

In modern environmental technology, data loggers play a decisive role in recording, monitoring and analysing environmental parameters. But not all data loggers are the same. A high-quality device is characterised by certain functions that are essential for effective environmental monitoring. Here are the seven most important functions that such a data logger should offer.

1. Robust design for use in the most adverse conditions

Environmental parameters such as temperature, humidity, gas concentration, dust and dirt vary greatly in different environments. A reliable data logger must therefore be robustly built to withstand the demands of field use, industrial plants or remote locations.

2. Compatibility with a wide range of sensors

Environmental engineers work with a variety of sensors that measure different parameters. A good data logger should therefore be compatible with a wide range of sensors to allow flexible customisation to specific project requirements. Wide compatibility enables environmental engineers to use the sensors required for their specific project.

3. Energy efficiency and battery life

As data loggers are often used in remote areas, a long battery life is crucial. A high-quality device must therefore be energy-efficient and have a battery that works reliably even under extreme conditions. For batteries to achieve a service life of several years, energy-efficient operation is the top priority.

4. Real-time monitoring and alarm functions

A high-quality data logger must be able to monitor data in real time and notify the user when problems occur. It should also offer remote access functions so that environmental engineers can access and analyse the data from anywhere in the world. Short measuring intervals and alarm options are essential here.

5. Long-term data recording and storage capacity

To be able to track environmental changes over a longer period of time, data loggers require sufficient storage capacity and the ability to record data over weeks, months or even years. For cost and efficiency reasons, system architecture considerations are crucial here. The data logger in the field records the measured values and sends them to a cloud at regular intervals. In the cloud, the storage capacity and computing power for analysis functions is much more cost-effective. It is important to ensure that the data is not archived in the cloud and that the complete raw data is available.

6. Scalability and expandability

To meet changing requirements, a data logger should be scalable and expandable. This means that it can be upgraded with additional sensors, for example, to add new measurement parameters. For ongoing improvements in functionality, it is essential to ensure that software and firmware updates are available over-the-air.

7. User-friendly software and interfaces

Last but not least, user-friendliness is crucial. A measurement system should be equipped with intuitive software that enables environmental engineers to easily visualise, analyse and interpret data. Interfaces such as graphical user interfaces and APIs should also be available to facilitate integration with other systems.

A high-quality data logger that offers these seven functions enables environmental engineers to collect and analyse accurate and reliable data for their environmental projects. By choosing such a device, you can ensure that your monitoring is effective and that you can make informed decisions for a modern, liveable world.

Choosing the right data logger is crucial for the success of environmental projects. Jellox is the right tool for demanding measurement campaigns in environmental technology.

Implementation of the EU Urban Waste Water Treatment Directive

The EU Urban Waste Water Treatment Directive protects the environment from harmful effects caused by the discharge of urban waste water; The guideline dates back to 1991 and is currently being revised; The planned innovations strengthen environmental protection. At the same time, this is accompanied by stricter requirements for sewer network operators, wastewater treatment plants and manufacturers.

In the following, we summarise the most important key points, show what the implementation of the EU Urban Waste Water Treatment Directive means for combined sewerage systems and provide an insight into the possible technologies that support implementation.

Heavy rainfall and effects on sewers: Data logger for heavy rain monitoring

Heavy rainfall events are occurring more frequently worldwide and pose an increasing challenge for wastewater systems. The intensity and frequency of heavy rainfall events are being intensified by climate change, which can lead to overloading of sewers. In this article, we analyse the effects of heavy rainfall on sewers and discuss possible solutions to the problem. In particular, we look at the opportunities and possibilities with data loggers.
