Kauj ruam 1: Cov ntaub ntawv

Yuav luag txhua cov ntaub ntawv xav tau rau txoj haujlwm no tuaj yeem yuav hauv khw online: DFRobot Rau qhov haujlwm no peb yuav xav tau:

-Solar vaj huam sib luag 9V

-Solar zog tswj

-DC-DC txhawb kev hloov pauv

-Solar Lipo charger

-LED ntsuas hluav taws xob

-cov kab

-3.7V Li-ion roj teeb

-various connectors

-SPST hloov 4x

-red thiab dub 4mm davhlau ya nyob twg losis tswvyim dabtsi

Kauj Ruam 2: Cov Qauv

Rau qhov haujlwm no kuv tau siv peb tus qauv sib txawv.

Hnub ci zog tswj

Cov qauv no muaj txiaj ntsig zoo vim tias nws tuaj yeem siv nrog cov khoom sib txawv. Yog li nws tuaj yeem siv tau hauv ntau txoj haujlwm.

Nws tuaj yeem siv nrog 7-30V hnub ci vaj huam sib luag, 3.7 Li-ion roj teeb lossis nrog USB cable.

Nws muaj plaub qhov sib txawv. Los ntawm 3.3V txog 12V, nrog 5V USB tso tawm thiab ntawm ib qho zis koj tuaj yeem xaiv qhov hluav taws xob 9V lossis 12V.

Kev qhia tshwj xeeb:

• Hnub ci input voltage: 7V ~ 30V Roj teeb nkag
• Cov tswv yim roj teeb: 3.7V ib leeg cell Li-polymer/Li-ion roj teeb

• Kev tswj fais fab:

  • OUT1 = 5V 1.5A;
  • OUT2 = 3.3V 1A;
  • OUT3 = 9V/12V 0.5A

DC-DC boost converter

Kuj tseem muaj txiaj ntsig zoo hloov pauv yog tias koj xav kom nrawm hloov pauv lub zog. Kev ntsuas hluav taws xob tau tswj nrog 2Mohm trimmer.

Kev qhia tshwj xeeb:

• Cov tswv yim hluav taws xob: 3.7-34V
• Cov zis hluav taws xob: 3.7-34V
• Max input tam sim no: 3AMax
• Lub zog: 15W

Hnub ci Lipo Charger

Tsim los rau them, nrog rau kev tiv thaiv thim rov qab polarity tiv thaiv. Nws muaj 2 LEDs rau them nqi qhia.

Kev qhia tshwj xeeb:

• Kev tawm tswv yim Voltage: 4.4 ~ 6V
• Them Tam Sim No: 500mA Max
• Them Txiav Tawm Voltage: 4.2V

Kauj Ruam 3: Lub Hwj Huam Fais Fab

Rau vaj tsev kuv siv cov khoom ntim yas ntim yas ntim lub thawv txuas hluav taws xob.

Ua ntej kuv mesaured txhua feem kom kuv paub txhua qhov ntev. Qhov kuv ntsia kos rau ntawm lub thawv sib txuas kom kuv pom tias txhua yam yuav zoo li cas. Thaum kuv zoo siab nrog tsim kuv pib ua qhov rau cov khoom.

Kuv siv 2 LED qhov ntsuas hluav taws xob ntsuas hluav taws xob. Ib qho yog tso tawm cov zis tso tawm thiab lwm qhov yog tso tawm 9V/12V tso zis, kom koj paub tias qhov hluav taws xob uas koj tau xaiv. Qhov ntsuas hluav taws xob LED no muaj txiaj ntsig zoo vim tias koj tsuas yog txuas lawv rau qhov ntsuas hluav taws xob thiab qhov ntawd yog nws. Tsuas yog qhov tsis zoo yog tias nws tsis qhia qhov hluav taws xob qis dua 2.8V.

Kuv siv 4mm lub davhlau ya nyob twg los txhawm rau kom koj tuaj yeem txuas cov khoom thauj mus rau lub zog siv. Cov khoom siv hluav taws xob no muaj 3 qhov hluav taws xob tso tawm (9V/12V, 5V thiab kho tau qhov tso tawm).

Kuv kuj tau ntxiv ob lub USB tso tawm kom koj tuaj yeem txuas ncaj qha rau koj Arduino lossis qee yam khoom siv. Nws kuj tseem siv tau rau them xov tooj. Qhov tso tawm zaum kawg yog siv rau kev them roj teeb (Li-po, Li-ion txog 4V.) Rau qhov kuv siv lub hnub ci roj teeb them.

Kauj ruam 4: Cov khoom siv

Lub zog hluav taws xob no tuaj yeem muab nrog ntau lub zog siv.

1. DC txiv neej jack

Nws tuaj yeem siv nrog DC jack cabel. Cov khoom siv no pom zoo yog tias koj xav tau cov peev txheej uas xav tau lub zog me ntsis ntxiv. Cov khoom siv no tseem muab kev ruaj ntseg tshaj plaws rau cov zis, uas txhais tau tias thaum koj txuas cov neeg siv hluav taws xob rau cov khoom siv, qhov hluav taws xob tso tawm tsis poob ntau.

2. 3.7V roj teeb

Koj tuaj yeem siv 3.7V ib leeg Li-polymer lossis Li-ion roj teeb. Hauv kuv qhov xwm txheej kuv siv 3.8V Li-ion roj teeb los ntawm kuv lub xov tooj qub. Nws tuaj yeem ua tiav nrog lub roj teeb no, tab sis tom qab ntawd nws muaj qee qhov kev txwv rau qhov tso tawm qhov hluav taws xob thiab tam sim no.

Kev tswj fais fab kev ua haujlwm tau zoo (3.7V roj teeb IN)

• OUT1: 86%@50%Thauj khoom
• OUT2: 92%@50%Thauj khoom
• OUT3 (9V Tawm): 89%@50%Load

Qhov ua tau zoo no yog qhov zoo thaum koj ua haujlwm nyob rau qee qhov uas koj tsis muaj hluav taws xob.

3. Hnub ci vaj huam sib luag

Rau qhov kev xaiv thib peb kuv xaiv hnub ci zog. Nws tuaj yeem siv nrog 7V-30V lub hnub ci vaj huam sib luag.

Hauv kuv qhov xwm txheej kuv siv 9V lub hnub ci vaj huam sib luag uas ua rau 220mA. Thaum xub thawj nws zoo li nws yuav muaj peev xwm ua tau lub hwj chim no. Tab sis thaum kuv ntsia ntsuas qhov haujlwm no nrog lub vaj huam sib luag hnub ci zoo heev kaw vim tias lub hnub ci vaj huam sib luag tsis tuaj yeem muab lub zog txaus txaus los muab txhua yam. Thaum ua kom pom kev zoo nws tsim tawm ib puag ncig 10V thiab txog 2.2W.

Yog li tom qab ntawd kuv ntsia kom them nyiaj nrog lwm cov khoom siv. Kuv ua ke 3.7V roj teeb thiab hnub ci vaj huam sib luag. Thaum kuaj nws pom tias cov roj teeb thiab lub hnub ci vaj huam sib luag ua ke muaj peev xwm ua tau lub zog siv hluav taws xob no.

Yog li txhawm rau muab qhov no koj yuav xav tau lub hnub ci vaj huam sib luag uas tuaj yeem tsim hluav taws xob ntau dua.

Piv txwv li:

Hnub ci nqi ua haujlwm tau zoo (18V SOLAR IN) ： 78%@1A

Yog tias koj muab nws nrog 18V lub hnub ci vaj huam sib luag, nws them tam sim no yuav nyob ib puag ncig 780mA.

Kauj Ruam 5: Hloov Kho Cov Qauv

Rau qhov haujlwm no kuv yuav tsum hloov kho me ntsis rau cov qauv. Txhua qhov kev hloov kho tau ua kom lub zog siv hluav taws xob tau yooj yim dua.

Ua ntej kuv hloov kho lub hnub ci tswj hwm tus qauv. Kuv tshem tawm qhov hloov pauv thawj smd thiab hloov nws nrog 3pin ib tus ncej ob npaug muab pov tseg. Qhov no ua rau kev hloov pauv ntawm 9V thiab 12V yooj yim dua thiab nws kuj zoo dua vim tias koj tuaj yeem hloov hloov mus rau lub tsev. Qhov kev hloov kho no tseem tuaj yeem pom ntawm daim duab. Tus tswj hwm lub zog hloov pauv muaj kev xaiv hloov ON/OFF cov txiaj ntsig. Kuv txuas cov pins no mus rau SPST hloov chaw kom koj tuaj yeem tswj tau cov txiaj ntsig

Kev hloov kho thib ob tau ua ntawm lub roj teeb them. Kuv tshem tawm thawj smd LEDs thiab hloov lawv nrog ib txwm liab thiab ntsuab LED.

Kauj Ruam 6: Xeem

Thaum kuv txuas txhua yam ua ke Kuv yuav tsum tau ntsuas yog tias txhua yam ua haujlwm raws li kuv tau npaj tseg.

Rau kev ntsuas qhov ntsuas hluav taws xob Kuv siv Vellemans multimeter.

Kuv ntsuas 5V tso zis. Ua ntej thaum tus thawj tswj hwm tau muab tsuas yog nrog 3.7V roj teeb thiab tom qab ntawd thaum nws tau siv nrog 10V adapter. Cov zis hluav taws xob zoo ib yam hauv ob qho tib si, feem ntau vim tias cov khoom tso tawm tsis tau thauj khoom.

Tom qab ntawd kuv ntsuas 12V thiab 9V cov zis. Kuv piv cov nqi hluav taws xob ntawm Velleman multimeter thiab LED voltage meter. Qhov sib txawv ntawm tus nqi multimeter thiab tus nqi ntsuas hluav taws xob LED ntawm 9V tau txog 0.03V thiab ntawm 12V nws yog li 0.1V. Yog li peb tuaj yeem hais tias qhov ntsuas qhov ntsuas hluav taws xob LED no yog qhov tseeb.

Kev hloov kho tau tuaj yeem siv rau lub zog LEDs, DC kiv cua lossis qee yam zoo li ntawd. Kuv sim nws nrog 3.5W lub twj tso kua dej.
