AVT1996. Bedlight - husiku mwenje controller ine inofamba sensor

26.05.2022 /

Iyo yakarongwa module panguva ino ndeye timer ine inofamba sensor, iyo iwe yaunogona kuchinjika kugadzirisa ma paramita ekushanda. Inoita seye otomatiki husiku mwenje uye yakagadzirirwa kushanda ne LED mitsetse. Kuonekwa kwekufamba mukamuri ine mwenje usina kujeka kunotanga chibatiso chenguva chinovhenekera zvakanaka sosi yemwenje ye LED yakabatana nekubuda. Mushure menguva yakatarwa ne potentiometer, kudzima kwayo kunononoka kunoitika.

Mutongi ndiyo mhinduro yakakwana yekamuri yekurara kana yevana. Iyo yese seti, pamwe neiyo LED strip yakaiswa pasi pemubhedha (chiedza cheusiku), ichaita kuti zvive nyore kumuka usiku uye kupa pfungwa yekuchengeteka. Chiedza chinovhenekera kana mushandisi apinda mukamuri kana kubata pasi netsoka. Chiedza chakavhenekerwa zvakanaka hachizomutsi vamwe vanhu uye chinouya zvakanaka kana mwana amuka usiku - kana patinenge tichida kumuka kwaari.

Dhidhiyo yedunhu remutongi inoratidzwa muMufananidzo 1. Yakabatanidzwa pakati pemagetsi uye mugamuchiri. Inofanirwa kupihwa nemagetsi anogara aripo kubva kubhatiri kana magetsi ane mutoro wazvino uno unoenderana nemutoro wakabatana. Diode D1 inodzivirira kubva pakubatanidza controller kune voltage yeiyo polarity isiriyo. Iyo voltage inogadziriswa ne IC1 (78L05). Chishandiso ichi chinodzorwa ne microcontroller IC2 (ATtiny25). Photoresistor PH1 inobata basa rechiedza sensor - nekuda kwairi, iyo inobuda ichaitwa chete mumamiriro asina kunaka emwenje.

1. Schematic diagram yeusiku chiedza regulator

Iyo yakakurumbira yakachipa HC-SR501 IR detector yakashandiswa seyekufamba sensor. Uwandu hwe sensor hunosvika 7 m, pakona yekutarisa ye100 degrees. A jumper pane sensor inokubvumira kuti uchinje maitiro aanoita kana kufamba kwaonekwa. Pachinzvimbo H, iyo detector inobuda inoramba ichishanda chero kufamba kwaonekwa. Muchinzvimbo L, inoisa sensor nenzira yekuti mushure mekufamba kunoonekwa - zvisinei kuti ichiri kucherechedzwa - iyo sensor inobuda inogadziriswa kwenguva yakatarwa ne potentiometer. Iyo sensor inogona kuvhurwa zvakare mushure memasekondi matatu. Iyo yekushanda ye detector muhuwandu hunosvika 3 kusvika ku3 m inogona kugadziriswa uchishandisa potentiometer iri pedyo nekugadzirisa jumper. Yechipiri potentiometer inogadzirisa nguva yekupindura ye detector mushure mokunge kufamba kwaonekwa (kubva pa7 kusvika ku5 seconds).

2. Dhiagiramu yegungano yemutongi wemwenje weusiku

Chinyorwa chezvinhu:

R1, R3, R4: 2,2 kΩ

R2: 1 kО

R5: 22 kО

PH1: photoresistor

C1, C2: 100uF/16V

C3, C4: 100 nF

IC1: 78L05

IC2: ATtiny25 (yakagadzirirwa)

T1: 3705 irl

D1: 1H4007

LED 1: LED

Motion sensor HC-SR501

KUPIWA, KUBUDZWA: DG301-5.0/2

Module oparesheni inotanga pakarepo mushure mekushandura magetsi ekupa. Iyo actuating element is transistor T1 mhando IRL3705. Nguva yekuvhenekesa yemwenje sosi yakabatana nekubuda inogona kugadziridzwa neiyo potentiometer PR1 muhuwandu hweanenge 15 masekonzi kusvika 8 maminetsi. Pese panoonekwa mafambiro, kuverenga pasi kunotanga patsva.

Iko kufamba kwekuona bhekoni basa rinoitwa ne LED. Iyo module inofanira kuunganidzwa pabhodhi redunhu rakadhindwa rine zviyero zve 33 × 65 mm, dhiyabhorosi yegungano inoratidzwa muMufananidzo 2. Gungano rinotanga nemasolder resistors uye zvimwe zviduku zviduku kubhodhi, uye inopera negungano. yestand, electrolytic capacitors, transistor, screw connections uye PIR module. Mushure mekusangana, iyo sisitimu inokurumidza kugadzirira kushandiswa, zvese zvinodikanwa ndeye gadziriso inosangana nezvinodiwa.
