SUMMARY

The discussion centers on the design specifications for a portable GaussMeter recorder intended for electromagnetic field (EMF) analysis. Key requirements include a size comparable to a laptop, a sampling rate of 1/5 seconds, and the ability to write data to various media such as USB sticks. The GaussMeter must measure fields in the milliGauss (mG) to tenths of Gauss range, enabling users to track EMF exposure throughout the day. The goal is to create an affordable, wearable device that facilitates extensive data collection for statistical analysis.

PREREQUISITES
  • Understanding of electromagnetic field (EMF) measurement principles
  • Familiarity with data logging techniques
  • Knowledge of portable device design considerations
  • Experience with data transfer methods (e.g., USB, MagCard)
NEXT STEPS
  • Research portable EMF measurement devices and their specifications
  • Explore data logging software compatible with USB data transfer
  • Investigate design principles for wearable technology
  • Learn about electromagnetic field exposure limits and health implications
USEFUL FOR

This discussion is beneficial for engineers, product designers, and researchers focused on EMF measurement technology, as well as health and safety professionals monitoring electromagnetic exposure levels.

How big/tough a portable recorder GaussMeter project would be?

It does not need to be light (tho not heavier/bigger than a laptop?) and it does not need to be nice looking. The realtime reading can be anything (Galva/LED/...) and sampling rate 1/second is fast enough (even too fast; as 1/5sec would be accurate IMO). It shall be able to write data to any media that can then be read on a PC (MagCard/usb stick-link/... whatever) at same sampling rate. Field range of Gaussmeter need to read in the mG to few tenths of Gauss.

Idea is to have a wearable EMF recorder for further analysis/statistic. Carried all day by different people would help define who face the most exposures and where they are. Cheap would be good too as it would be possible to make more samples to have better sampling of data.

Thanks for your time.

Thanks; I know those, but wanted to have a more 'adapted' system; hence designed to the needs. I already have some products like this and they are useful.
