Update on Magnetometer Construction

Progress has been slow with Magnetometer construction, however I now have the main PCB completed and installed in the box that will be installed in the garden.

The photo below shows the PCB installed:
 


The wiring from the circuit board is for:
  • Input Power
  • Power to the sensor and output from the sensor
  • Reset
  • Sensitivity settings
  • Output
The space on the left is for the Arduino that will be used for remote control of the Reset and the Sensitivity settings.

The next stage of the project will be to set up and test.

The box will be installed on a post in the garden with a cable running to the sensor which will be installed at the bottom of a hole in the ground to hopefully limit temperature drift of the sensor.

A second cable will run from the box to the computer shed where the data logger is installed along with the 12V power supply. An Ethernet cable will run to the Arduino.

Subject to weather, the system should be installed in a couple of weeks.
