Thaum twg los peb tawm ntawm peb lub rooj lossis chav, feem ntau peb tsis hnov qab tua lub teeb nyob ntawd. Qhov no ua rau poob hluav taws xob thiab nce hauv koj daim nqi hluav taws xob. Tab sis dab tsi, yog tias lub teeb tau tig mus txiav, tom qab koj tawm hauv chav. Yog hauv qhov kev qhia no peb yuav kawm paub yuav ua li cas thiaj li yooj yim Motion Activated teeb hloov, kom txuag hluav taws xob thiab txo koj cov nqi hluav taws xob.
Kauj ruam 1:
Txhawm rau hloov qhov no koj xav tau cov khoom hauv qab no.
1- PIR sensor X 1
2- Transistor BC547 X 1
3- Resistors 1K, 220R X 2
4- 5volt relay X 1
5- daim PCB X 1
6- Lub xov tooj ntawm tes qub/5volt SMPS X1
Saib ntawm PIR sensor, muaj ob lub zog loj nyob ntawd. Ib sab laug yog txhawm rau kho qhov rhiab ntawm lub sensor thiab sab xis yog txhawm rau kho lub sijhawm tso zis. Tig sab laug potentiometer mus rau sab xis kom txog thaum kawg, qhov no yuav teeb tsa lub siab rhiab heev ntawm lub sensor. Thiab Tig txoj cai potentiometer txog rau txoj haujlwm nruab nrab, nws yuav teeb tsa lub sijhawm mem tes ntawm 2 txog 3 feeb. Kuj tseem muaj jumper rau teeb tsa rov qab, muab tso rau ntawm txoj haujlwm siab. Tsis tas li ntawd muaj 3 tus pin rau cuam tshuam lub sensor nrog ib qho microcontroller lossis lwm yam Circuit Court. Thawj tus pin yog hauv av, tom ntej yog Tawm Tawm, thiab tus kawg yog Vcc.
Kauj Ruam 2: Kev piav qhia Circuit:
PIR sensor lub hauv paus tus pin txuas rau hauv av, Vcc txuas nrog rau +5volt zog thiab tso tus pin txuas nrog lub hauv paus ntawm transistor los ntawm resistor R1. Cov kws sau khoom sib txuas txuas nrog ib kawg ntawm cov xa xov txuas thiab lwm qhov kawg ntawm kev xa xov txuas nrog 5volt zog. Diode d1 txuas nrog hla kev xa tawm. Ib kawg ntawm lub teeb txuas nrog lub xaim hluav taws xob nws tuaj yeem nyob lossis tsis xaim hlau, lwm qhov kawg ntawm lub teeb txuas nrog TSIS MUAJ kev sib cuag ntawm kev xa xov. Kev sib cuag sib txuas ntawm kev sib txuas tau txuas nrog lwm lub xov hlau ntawm cov khoom siv hluav taws xob. NC kev sib cuag ntawm kev xa tawm yuav tseem tsis txuas nrog. Txhawm rau muab lub zog rau hauv Circuit Court Kuv siv lub xov tooj ntawm tes qub them lub rooj sib tham hauv Circuit Court lossis koj tuaj yeem siv ib qho 5 volt SMPS chav.
Thaum PIR sensor nkag siab ib qho lus tsa suab hauv nws lub zeem muag pom kev, nws ua rau muaj mem tes siab ntawm nws tus pin tso tawm. Raws li kuv txuas tus pin tso tawm no mus rau lub hauv paus transistors, nws mus nyob rau hauv hom saturation, uas ua rau qis dua cov khoom siv hluav taws xob, kwv yees li 0 volts. Yog li cov transistor ua raws li luv Circuit Court, ua rau cov dej ntws tam sim no los ntawm cov xa hluav taws xob. Vim tias qhov kev sib cuag sib txuas ntawm kev sib txuas tau hloov pauv mus rau TSIS tau hu, qhov kev ua no ua tiav AC Circuit thiab tig lub teeb.
Kauj Ruam 3: Muab Cov Cheeb Tsam thiab Cov Lej
Nqa ib daim PCB tso tag nrho cov khoom ntawm qhov chaw tsim nyog rau nws thiab muab lawv pov rau hauv raws li daim duab qhia chaw. Solder charger xov hlau zoo ib qho thiab ib qho tsis zoo rau PCB. Txuas cov xov hlau rau teeb thiab rau cov khoom siv hluav taws xob raws li qhia. Hauv kuv qhov teeb meem daj yog rau teeb thiab cov xov hlau dub yog rau cov khoom siv hluav taws xob AC. Muab tag nrho cov kab hluav taws xob no tso rau hauv ib lub thawv thiab kaw nws. Kuv ua lub thawv no los ntawm cov duab los qhia, koj tuaj yeem siv lub thawv twg haum raws li cov ntawv ntim. Thiab tag nrho cov set
Txhim kho nws ntawm txoj haujlwm uas tus neeg saib xyuas tuaj yeem saib koj. Txuas cov xov hluav taws xob tso rau lub teeb thiab cov xov hluav taws xob nkag mus rau cov khoom siv hluav taws xob, thaum txuas nws nrog lub tshuab hluav taws xob kom ntseeg tau tias cov khoom siv hluav taws xob raug tua.
Txij li nws ua haujlwm ntawm 220 volt ac Ua tib zoo saib xyuas thaum tuav lub Circuit no, ua tsis raug ntawm nws, tuaj yeem ua rau koj poob hluav taws xob hnyav kuj tuaj yeem ua rau raug mob tuag taus
Vam tias koj pom qhov no muaj txiaj ntsig. yog tias yog, nyiam nws, qhia tawm, tawm tswv yim koj tsis ntseeg. Rau ntau cov haujlwm zoo li no, ua raws kuv! Txhawb nqa kuv cov channel hauv YouTube.
