Yuav ua li cas siv qhov kev ncua deb sensor

Qhov kev ncua deb sensor tsuas yog suav nrog kev teeb tsa kev ntsuas thiab siv. ‌‌

Kev Teem caij calibration
Ntau lawm teeb tsa:

Chaw {{{{0} V Tso zis: Nias tus RUCTs BUCE (lub ntsuas thiab lub phiaj phiaj dav hlau sib txuas), nias " K "rau li 5 feeb kom txog thaum lub LED tawm mus, thiab qhov kev ncua deb ntawm lub sensor thiab lub hom phiaj yog teem rau qhov kev ncua deb ntawm 0V tso zis taw tes.
Teeb Meem 5V Cov Khoom Taw Qhia: Nias tus hloov "K" rau li 1 thib ob, lub LED tig ntsuab, nias "rau li 5 vib nas this kom txog thaum lub LED tawm mus, thiab qhov kev ncua deb ntawm lub sensor Thiab lub hom phiaj yog teeb tsa rau qhov kev ncua deb ntawm 5V tso zis taw tes.
Teeb tsa hloov cov zis tso zis: Nias tus hloov "k" peb zaug rau txog 1 thib ob, lub LED tig rov qab daj, nias "rau li 5 vib nas this kom txog thaum lub LED tawm mus, thiab qhov kev ncua deb ntawm Lub sensor thiab lub hom phiaj yog teeb tsa rau qhov kev ncua deb ntawm kev hloov tso zis tso zis. Txoj kev hloov tso zis taw tes hysteresis yog 10 hli.
Teeb tsa hloov cov lus tawm hauv lub xeev: lub chaw teeb tsa Hoobkas yog "feem ntau qhib". Disconnect lub sensor fais fab mov, nias "los txuas lub zog hluav taws xob, tso tawm" k ", hloov tawm lub xeev hloov mus rau" feem ntau kaw ". Rov ua txoj haujlwm los hloov lub tshuab hloov tawm lub xeev.

Qhov taw qhia kev ua haujlwm
