Wireless Data Acquisition System with Low Magnetic Contamination

The aim of the work is a development of a wireless data acquisition system for three-channel fluxgate magnetometer based on experiences by tests in the bachelor work “Three channel AD converter for fluxgate magnetometer”. The design is constructed as a system with low magnetic contamination. The constructed system was tested on the basic parameters like noise performance, temperature change and linearity. At the end it was tested with connection to magnetometer.

Concept…
RF module, DAQ module and MCU module…
Battery module with charger…
Complete setup
RF part was tricky…
Investigating Li-pol battery magnetic cleanliness
Final testing, in this case with analog accelerometers using non-magnetic positioning platform (scalar calibration of the 3D accelerometer)
