Example	Piv txwv tias tus nqi tseem ceeb yog teem rau 10m / s2, qhov Active Threshold (los yog InActive Threshold) yuav tsum tau teeb tsa yog 10/9.8/0.0625=16.32 Active Threshold (los yog InActiveThreshold) yuav tsum tau teeb tsa tus lej ua 16. Nco tseg: Thaum configuration, xyuas kom meej tias Active Threshold yuav tsum ntau dua qhov InActive Threshold.

5.2 Calibration

Lub accelerometer yog ib qho qauv siv tshuab uas muaj cov khoom uas tuaj yeem txav tau yooj yim.
Cov khoom txav no yog qhov nkag siab zoo rau cov neeg kho tshuab kev ntxhov siab, deb tshaj li cov khoom siv hluav taws xob hauv xeev.
Lub 0g offset yog ib qho tseem ceeb accelerometer qhov taw qhia vim nws txhais cov hauv paus siv los ntsuas acceleration.
Cov neeg siv yuav tsum tau nruab thiab qhib R718E ua ntej.
1 feeb tom qab koom nrog lub network, R718EC yuav hloov pauv
los ntawm calibration. Cov ntaub ntawv qhia ua ntej sib txawv calibration tuaj yeem tsis quav ntsej.
Yog tias cov neeg siv xav kho lub cuab yeej txoj haujlwm, nws yuav tsum raug txiav tawm ntawm lub zog hluav taws xob rau 1 feeb thiab tig nws kom tau txais kev sib txawv ntawm qhov ntsuas.
Tom qab deviating los ntawm calibration, qhov qhia txog peb-axis acceleration tus nqi yuav nyob rau hauv 1m / s², uas txhais tau tias cov cuab yeej tseem nyob. (Yog tias tus nqi siab dua 1m / s², cov neeg siv yuav tsum rov ua cov lus qhia saum toj no kom txog thaum tus nqi nyob hauv 1m / s².)
Yuav kom muaj qhov tseeb tshaj tawm tus nqi, txoj hauj lwm ntawm lub sensor yuav tsum tau kho tom qab deviating los ntawm calibration.

Ntau yam ntawm Netvox li yog siv los ntawm 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) roj teeb uas muaj ntau yam advantages suav nrog tus nqi qis tus kheej tawm thiab siab zog ceev.
Txawm li cas los xij, thawj cov roj teeb lithium zoo li Li-SOCl2 roj teeb yuav tsim cov txheej txheem passivation raws li cov tshuaj tiv thaiv ntawm lithium anode thiab thionyl chloride yog tias lawv khaws cia rau lub sijhawm ntev lossis yog tias qhov ntsuas kub siab dhau lawm. Cov txheej txheem lithium chloride no tiv thaiv tus kheej tawm sai sai los ntawm cov tshuaj tiv thaiv txuas ntxiv ntawm lithium thiab thionyl chloride, tab sis roj teeb passivation kuj tseem tuaj yeem ua rau vol.tage ncua sij hawm thaum cov roj teeb tau muab tso rau hauv kev ua haujlwm, thiab peb cov khoom siv yuav tsis ua haujlwm raug rau qhov xwm txheej no.
Yog li ntawd, thov nco ntsoov cov khoom siv roj teeb los ntawm cov neeg muag khoom txhim khu kev qha, thiab nws tau hais tias yog tias lub sijhawm khaws cia ntau tshaj ib hlis txij li hnub tsim cov roj teeb, tag nrho cov roj teeb yuav tsum tau qhib.
Yog tias ntsib qhov teeb meem ntawm roj teeb passivation, cov neeg siv tuaj yeem qhib lub roj teeb kom tshem tawm cov roj teeb hysteresis.

ER14505 Roj teeb Passivation:

8.1 Txhawm rau txiav txim siab seb lub roj teeb puas yuav tsum tau ua kom ua haujlwm
Txuas lub roj teeb tshiab ER14505 mus rau lub resistor nyob rau hauv parallel, thiab xyuas cov voltage ntawm lub voj voog.
Yog voltage yog qis dua 3.3V, nws txhais tau tias lub roj teeb yuav tsum tau ua kom.

8.2 Yuav ua li cas qhib lub roj teeb
ib. Txuas lub roj teeb rau lub resistor nyob rau hauv parallel
b. Khaws qhov kev sib txuas rau 5 ~ 8 feeb
c. Lub voltage ntawm Circuit Court yuav tsum yog ≧3.3, qhia tias ua kom tiav.

Hom	Load Resistance	Lub Sijhawm Ua Haujlwm	Ua kom tam sim no
NHTONE	165 Ω	5 feeb	20 mA
RAMWAY	67 Ω	8 feeb	50 mA
EVE	67 Ω	8 feeb	50 mA
SAFT	67 Ω	8 feeb	50 mA

Nco tseg:
Yog tias koj yuav cov roj teeb los ntawm lwm yam tshaj li plaub lub tuam txhab saum toj no, tom qab ntawd lub sijhawm ua kom lub roj teeb, ua kom tam sim no, thiab qhov yuav tsum tau ua haujlwm yuav tsum tau ua raws li cov lus tshaj tawm ntawm txhua lub chaw tsim khoom.

Cov Lus Qhia Tseem Ceeb Saib Xyuas

Ua tib zoo saib xyuas cov hauv qab no kom ua tiav qhov zoo tshaj plaws txij nkawm ntawm cov khoom:

• Khaws lub cuab yeej kom qhuav. Los nag, dej noo, lossis cov kua dej yuav muaj cov ntxhia thiab yog li ua rau cov hluav taws xob hluav taws xob. Yog tias lub cuab yeej ntub dej, thov kom qhuav tag.
• Tsis txhob siv lossis khaws cov cuab yeej hauv qhov chaw muaj plua plav lossis qias neeg. Nws tuaj yeem ua rau nws cov khoom sib cais thiab cov khoom siv hluav taws xob puas.
• Tsis txhob cia lub cuab yeej nyob rau hauv cov cua kub heev. Qhov kub thiab txias tuaj yeem ua rau lub neej luv luv ntawm cov khoom siv hluav taws xob, rhuav tshem cov roj teeb, thiab deform lossis yaj qee qhov yas.
• Tsis txhob khaws cov cuab yeej rau hauv qhov chaw txias heev. Txwv tsis pub, thaum kub nce mus rau qhov kub thiab txias, noo noo yuav tsim sab hauv, uas yuav ua kom puas lub rooj tsavxwm.
• Tsis txhob muab pov, khob lossis co lub cuab yeej. Kev tuav tsis zoo ntawm cov cuab yeej tuaj yeem rhuav tshem cov vaj huam sib luag sab hauv thiab cov qauv tsim.
• Tsis txhob ntxuav lub cuab yeej nrog cov tshuaj muaj zog, tshuaj detergents, lossis cov tshuaj detergents.
• Tsis txhob siv lub cuab yeej nrog cov xim. Smudges yuav thaiv lub cuab yeej thiab cuam tshuam rau kev ua haujlwm.
• Tsis txhob muab lub roj teeb tso rau hauv qhov hluav taws kub, lossis lub roj teeb yuav tawg. Cov roj teeb puas tseem tuaj yeem tawg.

Tag nrho cov saum toj no siv rau koj lub cuab yeej, roj teeb, thiab cov khoom siv ntxiv.
Yog tias ib qho cuab yeej ua haujlwm tsis zoo, thov coj mus rau qhov chaw pabcuam uas tau tso cai nyob ze tshaj plaws los kho.
