Vytautas Markevičius, Dangirutis Navikas · Elektronika ir Elektrotechnika · 2011
There are presented experimental research results of AMR sensors (Honeywell HMC1022, MEMSIC MMC314xMS and STMicroelectronics LSM303DLH) thermo-stability. The experiment results show that not all sensors have temperature characteristics that are declared by manufacturer. Adaptive thermo-compensation algorithm pas proposed. Proposed method avoids need of additional AMR sensors calibration and selection and allows decreasing measurement errors in a wide temperature range (up to 100 oC).
