ARDUINO RPI-1031 4 Yo'nalish sensori

Ishlash printsipi

1. Optika printsiplariga asoslanib, uning ichki qismida 1 dona uchun LED, 2 dona uchun fotosensitiv qabul qiluvchi triod, ikkinchi tomonida bitta silindrsimon soya mavjud; rasmda ko'rsatilganidek:
   
   Elektr sxemasi
   
2. LEDni ushlab turish uchun silindrsimon soyada va fotosensitiv qabul qiluvchi trubka RPl-1031 joriy holatini aniqlash uchun mo'ljallangan.
   
3. RPl-1031 quyida ko'rsatilgan holatga aylanganda, LED soya bilan soyalanadi; va ikkita fotosensitiv qabul qiluvchi triod yorug'likni qabul qila olmaydi; ular o'chirilgan holatda bo'ladi. chiqish past daraja; ikkita GPIO porti ikkalasi ham past darajani chiqaradi.
   
4. RPl-1031 quyida ko'rsatilgan holatga aylanganda, fotosensitiv triodlardan biri soyada bo'lgan, LED chiqaradigan yorug'likni faqat boshqasi qabul qilishi mumkin; bu yuqoridagi fotosensitiv triod yoqilgan va yon tomondagi fotosensitiv triod o'chirilganligini anglatadi; keyin ikkita GPIO porti mos ravishda yuqori va past darajani chiqaradi.
   
5. RPl-1031 quyida ko'rsatilgan holatga aylanganda, soya soya qilmaydi, diod porlaydi, ikkita fotosensitiv triod yorug'likni qabul qilishi mumkin; keyin ularning barchasi yoqilgan bo'ladi. Ikkita GPIO portining ikkalasi ham yuqori darajada chiqadi.
   
6. RPl-1031 quyida ko'rsatilgan holatga aylanganda. Bu holat tavsifga ziddir 4 ikkita GPIO portining chiqish darajasi o'zaro bog'langan bo'ladi.
