Kuv pom ib pawg ntawm PIR sensors ntawm eBay. Lawv tau teeb tsa ntawm lub pcb uas tau tsim los rau teeb tsa tes dawb rau cov xov tooj ntawm tes. Kuv nyiam piav qhia ntawm no yuav ua li cas npaj lub ntsuas pa rau kev siv hauv cov phiaj xwm neeg hlau. Yog tias koj tsis paub PIR sensor yog dab tsi, tsuas yog saib Wikipedia https://en.wikipedia.org/wiki/Passive_infrared_sensor. Cov khoom uas cov laug cam tuaj ntawm no tuaj yeem yuav ntawm no https://www.greasemonkeyconversions.com/10609/Com_N_Sense_Hands-Free_Kit_(Nokia_3310_etc).shtml. Kuv yuav cov laug cam los ntawm tus muag khoom npe "kalleb" ntawm eBay. Kev tshawb fawb ntawm tus muag khoom lossis rau cov ncauj lus "PIR INFRARED SENSOR" ua rau qhov kev thov. Nws tseem muaj qee cov laug cam. Ntawm cov laug cam koj tseem tuaj yeem pom qee qhov hloov pauv qhov hloov pauv. Kuv siv lawv hauv lwm qhov haujlwm https://www.instructables.com/id/SLVOL8FFBGW8AF4/ qhov twg kuv xav tau kom tau--15V tawm ntawm +5V cov khoom. Muaj lwm yam khoom muaj txiaj ntsig ib yam nkaus, tab sis ntawm no peb tsuas yog xav tau lub pir sensor thiab op amp uas npaj pir lub teeb liab rau kev siv ncaj qha nrog microprocessor.

Kauj Ruam 1: Yam Koj Xav Tau

Ua ntej tshaj plaws koj xav tau pir board.

rau kev npaj: - cov hlau txuas - tin -solder - jigsaw rau kev sim: - lub tshuab fais fab ntawm lub tshuab nrog +5V tso tawm (0.2A tam sim no txaus rau ntsuas) - ntsuas qhov ntsuas hluav taws xob - qee qhov xov hlau

Kauj Ruam 2: Txiav Pir Sensor Los Ntawm Pawg Thawj Coj

Peb xav tau tsuas yog lub pir sensor thiab hluav taws xob uas npaj cov cim teeb liab rau kev siv nrog microprocessor. Lub ntsuas hluav taws xob thiab lub tshuab hluav taws xob ua haujlwm tau zoo, nws tsuas yog xav tau ib leeg +5V thiab nws muab lub teeb liab uas tuaj yeem pub rau hauv microprocessor. Yog li nws ua rau kev nkag siab tsis txhob desolder lub sensor thiab tsim txhua yam khoom los ntawm koj tus kheej.

Tsuas yog txiav daim pcb uas koj xav tau. Muaj qhov "txuag" txiav uas koj tuaj yeem pom ntawm daim duab, kos ua kab liab. Yog tias koj txiav qhov ntawd txhua yam yuav ua haujlwm zoo tom qab txiav. Koj tseem tau txais qee qhov kev teeb tsa zoo. Yog tias koj xav txuag chaw, lossis hnyav, koj tuaj yeem txiav raws txoj kab daj. Yog tias koj ua li ntawd koj tseem yuav txiav cov hlau uas nqa +5V nruab nrab ntawm pir sensor thiab op amp. Cov xov hlau khiav hauv pcb. Nws zoo li yog plaub txheej pcb. Qhov no tsis muaj teeb meem yog tias koj tsuas yog hloov nws nrog xaim me me uas koj tau muab tso rau ntawm tus pin ntawm pir sensor thiab tus pin 8 ntawm op amp.

Kauj Ruam 3: Xeem

Rau kev sim koj yuav tsum ntxiv cov xov hlau rau lub zog thiab xaim uas nqa cov teeb liab tso tawm.

Muab +5V rau ntawm lub rooj tsavxwm thiab txuas lub ntsuas hluav taws xob mus rau tus pin tso tawm. Tsiv koj txhais tes ze lub ntsuas pa ua rau +5V mem tes ntawm qhov ntsuas hluav taws xob. Yog tias koj khaws koj txhais tes tseem qhov hluav taws xob poob qis. Yog tias koj txav koj txhais tes nce qhov hluav taws xob. Tus qauv muab teeb liab rau kev txav mus los. Qhov no ua haujlwm nrog txhua yam khoom uas tso tawm hluav taws xob infrared. Tus qauv muab cov mem tes thaum nws pom qhov sib txawv ntawm qhov hluav taws xob infrared ntawm cov khoom nws taw tes rau. Kuv tau sim nrog kuv lub cev tib neeg, nrog cov khoom ua kom sov, zoo li cov hlau txuas thiab txawm tias yog tus kav yas. Txhua yam no uas pom. Qee qhov pom pom deb ntawm lub ntsuas hluav taws xob thiab qee qhov yog tias cov khoom ua tsov rog nyob ze los ntawm lub ntsuas. Kuv tau ua qee qhov kev sim nrog lub cuab yeej. Kuv pom tias nws ua haujlwm los ntawm kwv yees li 25cm mus txog ze li 0cm. Ntawm 25 cm nws pom cov peev txheej loj, zoo li tib neeg. Ib txhais tes ntawm ib tus neeg raug kuaj pom ntawm thaj tsam li 10cm. Yog tias kuv siv tus pas hlau dab ua kom sov li ntawm 350 degrees Celsius, nws tau kuaj pom ntawm 25cm. Ib txoj cai yas raug kuaj pom ntawm 5cm. Tus ntsia hlau ntsia ntawm qhov deb tib yam. Lub ntsuas ntsuas muab qhov sib txawv ntawm qhov sib txawv ntawm qhov hluav taws xob infrared nws "pom" … uas ua rau kuv xav tias tseem tuaj yeem pom cov dej khov. Tab sis lawv tsis ua. Kuv puas ua raws txoj kev xav tsis raug?;-) Kuv xav tias qhov rhiab heev tuaj yeem ua kom zoo dua siv qhov muag lo ntsiab muag. Cov neeg ntes txav chaw hauv tsev siv Fresnel lo ntsiab muag txhawm rau txheeb xyuas thaj chaw kom pom.
