magnetometer

[miichant]

hello everyone i want to build a magnetometer as okm is anybody can help me

[abdou2014]

[miichant]

thank you very much abdou2014 can i use a software like Visualizer3D with this magnetometer

[taxma1981]

today i finished the magnetometer with the raspberry pi3it is perfekt like a professional detector

[taxma1981]

why you smile?

[abdou2014]

it's my little daughter who sent you these smiles nice work

[taxma1981]

:χαχαχα:ok sorry!thanks

I see arduino uno , HMC5883L and RASPBERRY PI3
how is the connection made , you code with phyton and the detection disk

[taxma1981]

I can not explane from hear,you need a programmer

[taxma1981]

The sensor it is a flc 100 and a mcp 3424

[abdou2014]

Give us all details and schematics circuits

[taxma1981]

I can not:χαχαχα:

The FLC100_shield supports the operation of the FLC100 magnetometer for AuroraWatchNet. The shield can be built to operate in one of several modes.

Using the remote FLC100 PCB, digital signals are sent to/from the board over I2C. The remote board generates the 5V supply whilst the FLC100 shield generates the 3.3V supply. The MCP3424 ADC resides on the remote board. This mode allows the sensor and critical analogue electronics to be located in a temperature-stabilised location (eg buried). Two or three axis operation is possible by configuring the MCP3424 ADCs to use different I2C addresses. This is the intended mode of operation.
Fully self-contained, with the FLC100 and MCP3424 ADC located on-board. The shield provides both 3.3V and 5V supplies from an external 3V battery. This mode is the most compact but may expose the sensor to higher temperature variations and stray magnetic interference.
Using the remote FLC100 PCB, analogue signals are sent to the MCP3424 ADC on the shield. This mode is likely to result in sub-optimal performance and was provided in case of difficulties driving I2C signals over the required distance; the concern appears unfounded.

hello, I need the circuit of the differential amplifier which connects between the two sensors FLC or FGM thank you very much

[abdou2014]

thank you, but that's not what I'm looking for, it's a diagram that synchronizes the two sensors for more sensitivity
