Lub Teeb Cim yog cov khoom siv hluav taws xob uas siv LDR (lub teeb nyob ntawm tus tiv thaiv) txhawm rau txhawm rau txo qis lub teeb thiab teeb lub LED ib zaug nws tau tsaus qhov no yog qhov piv txwv zoo ntawm LDR hauv kev nqis tes ua.

PCB no tuaj yeem siv ua khoom siv tau.

Kauj Ruam 3: Kev Ntseeg:

Thaum raug rau lub teeb ci, tus kws kho qhov muag tsis kam yog qhov tsawg heev Nws poob rau ib puag ncig 20-30 KΩ. Tam sim no taug kev los ntawm 100 KΩ resistor thiab tom qab ntawd muaj 2 txoj hauv kev.. Cov hauv paus ntawm transistor rau cov collecor muaj kev tiv thaiv ib puag ncig 400 KΩ. Tam sim no ib txwm siv txoj hauv kev tsis muaj zog tiv thaiv. Thaum photoresitor raug rau lub teeb ci, nws tiv taus yog li 20-30 kΩ, uas yog qhov tsawg dua li 400 kΩ ntawm kev tiv thaiv lub hauv paus ntawm transistor muaj. Yog li ntawd, feem ntau ntawm cov tam sim no yuav dhau los ntawm photoresistor thiab tsawg heev yuav mus rau lub hauv paus ntawm transistor. So lub hauv paus ntawm transistor yog hla, Yog li, lub transistor tsis tau txais tam sim no txaus kom qhib thiab lub zog ntawm LED. Yog li ntawd lub LED tawm thaum muaj teeb pom kev ntau nyob ib puag ncig.

Thaum nws tsaus ntuj, photoresistor qhov kev tawm tsam dhau mus heev. Nws tiv taus mus txog 2 MΩ Qhov no tsim txoj hauv kev tiv taus siab heev, vim qhov no, feem ntau ntawm qhov tam sim no yuav dhau los ntawm lub hauv paus ntawm transistor. Nws txhais tau tias tam sim no tsis mus los ntawm photoresistor thaum nws tsaus ntuj.
