PNI RM3100 High Precision 3 Axis Digital Electronic Compass Magnetic Field Sensor Magnetometer Geomagnetic Transducer Module With SPI Interface

Q: Does this sensor have enough sensitivity to detect the ground geomagnetic field indicative of aurora?

Sorry, can't help you there. I can tell you very roughtly it's about 10x more sensitive than traditional hall sensors and 10x less sensitive than expensive magnetic dip sensors. I've still yet to test my project with very weak fields.

Q: Exactly what do i need to connect this to a windows 7 pc? what cable is needed?

Hi Richard, Thanks for reahcing out. The RM3100 chip is compatible with MCU, such as STM32. RM3100 connection with STM32, wiring methods as below: VCC - VCC, GND - GND, CLK- SCLK, MISO - MOSI, MOSI- MISO, SSN - SNN. The STM32 connected with RM3100, the interface can be connected with PC. USB-TTLTX--------connect--------STM32's PA10 USB-TTLRX--------connect--------STM32's PA9 VCC----------------VCC GND----------------GND The data sheet can be download from the link., https://wiki.wit-motion.com/english/doku.php?id=rm3100 Follow the instruction of connection shown in the manual would be hugely helpful. Keep me updated if you need any further assist. Always online to serve your queries.

Q: is it pre-calibrated for self-caused hard-iron effect?

Hello sir, Thanks a lot for reaching out and let me know your concern. It is not pre-calibrated. I consulted with my engineering team but we do not quite understand the hard-iron effect. You can buy a sample for trial testing. If you find it is not suitable, 100% refund policy is provided. Hope above info finds you well. Regards, Kyle WitMotion Team

Q: The sensor came with a reference card with a scan code that took me to the Witmotion GitHub main page, but no repo for the RM3100 - right?

Yes, there is no sample program for this device. You can refer to this instruction, the link is as follows: https://drive.google.com/file/d/1BYzB4e6G86g-4NvGCTG_Vd_72EXbtPFD/view?usp=drive_link
