The SM225-10E smart magnetometer from NVE is designed to provide precise magnetic field measurements, detecting magnets even over 50mm away. The sensors combine precise Tunneling
Magnetoresistance (TMR) sensor elements with easy-to-use
digital signal processing, Unlike awkward, old-fashioned Hall-effect sensors, TMR is
sensitive in-plane for optimal current sensing and easy
mechanical interfaces. TMR also provides more sensitivity,
higher precision (2%), higher speed (15kSps), and lower noise than Hall. This magnetometer is a digital device with a 4-wire SPI interface, providing magnetic field data and a way to set parameters such as thresholds. The SM225-10E sensor comes factory calibrated to high accuracy, with the calibration coefficients stored in internal non-volatile memory and is available in ultra-miniature TDFN6 packaging (2.5 x 2.5mm footprint).
