HWT901B Ahrs IMU Sensor
Le Saosaoa Malosi, Saosaoa Angular, Angle , Magnetic filed & Su'esu'ega o le Ea
O le HWT901B o se masini faʻalogo IMU, suʻesuʻeina le saoasaoa, saosaoa angular, tulimanu, maneta filed fa'apea fo'i ma le mamafa o le ea. Ole fale mautu ma le la'ititi la'ititi e fa'apena ona fetaui lelei mo fa'aoga fa'apisinisi e pei ole mata'ituina o tulaga ma le tausiga fa'apitoa. O le faʻatulagaina o le masini e mafai ai e le tagata faʻatau ona faʻafesoʻotaʻi le tele o ituaiga o talosaga e ala i le faʻamatalaina o faʻamatalaga faʻamatalaga e ala i algorithms atamai ma Kalman filtering.

O le igoa faasaienisi HWT901B o le AHRS IMU sensor. O se masini e fuaina le 3-axis angle, angular velocity, acceleration, magnetic field ma le mamafa o le ea. O lona malosi o loʻo taoto i le algorithm lea e mafai ona fuafua saʻo le tolu-axis angle.
HWT901B o loʻo faʻafaigaluegaina i le mea e manaʻomia ai le saʻo sili ona maualuga. HWT901B ofo atu le tele o advantage sili atu i le masini tauva:
- Faʻamafanafanaina mo sili ona lelei faʻamatalaga avanoa: fou WITMOTION pateni leai-faʻaaogaina otometi mauaina calibration algorithm outperforms masani accelerometer sensor
- Sa'o maualuga Roll Pitch Yaw (XYZ axis) Fa'asaosaoa + Saosaoa Angular + Angle + Maneta Fa'amaneta + O'omiga o le Ea
- Tau maualalo o le umiaina: mamao diagnostics ma olaga atoa lagolago faʻapitoa e le WITMOTION 'au au
- Atiaʻe aʻoaʻoga: tuʻuina atu tusi lesona, faʻamatalaga, ata vitio, polokalama PC, telefoni feaveaʻi APP ma 51 serial, STM32, Arduino, ma Matlab sample code, feso'ota'iga protocol
- WITMOTION sensors na viʻia e le faitau afe o inisinia o se fautuaina uiga fuataga fofo
Vaega
- Fausia-i totonu o le WT901B module, mo auiliiliga auiliili, faamolemole taga'i i faatonuga.
- Ole fua ole pa'u o lenei masini e 9600 ma e mafai ona suia.
- O le fa'aoga o lenei oloa e na'o le ta'ita'i atu i se uafu fa'asologa
- O le module e aofia ai se gyroscope maualuga maualuga, accelerometer, geomagnetic field ma le barometer sensor. E mafai e le oloa ona foia vave le gaioiga o le gaioiga o le module i le taimi nei e ala i le faʻaaogaina o le microprocessor maualuga, fofo faʻamalosia ma le Kalman filter algorithm.
- Ole fa'atekonolosi fa'atekinolosi fa'atekinolosi o lenei oloa e mafai ona fa'aitiitia lelei le pisa o fua ma fa'aleleia le sa'o o fua.
- Ole maualuga ole 200Hz ole fua ole fa'amatalaga. O mea e maua mai e mafai ona filifilia fa'apitoa, o le saoasaoa o le gaosiga 0.2HZ~ 200HZ fetu'una'i.
