HC-SR04 Ultrasonic sensor haqida

Sensorda quyidagi 4 ta pin mavjud:
1. VCC – 5V kuchlanish manbasi
2. Trig – Trigger signali (kirish)
3. Echo – Javob signali (chiqish)
4. GND – Yer (ground)

Ishlash prinsipi:

1. Trig pin orqali 10 mikrosekundlik HIGH signal yuboriladi

2. Sensor ultratovush to‘lqinini chiqaradi (40 kHz chastotada)

3. To‘lqin ob’ektga tegib qaytgach, Echo pin HIGH bo‘ladi

4. Echo pin HIGH bo‘lib turgan vaqt — to‘lqinning borib kelish vaqti

5. Ushbu vaqt asosida masofa hisoblanadi:
\text{Masofa} = \frac{\text{Vaqt} \times \text{To‘lqin tezligi (340 m/s)}}{2}

HC-SR04 Texnik xususiyatlari:

Xususiyat Qiymat:
Ishlash kuchlanishi 5V DC
Ishlash toki ~15 mA
Ishlash chastotasi 40 kHz
O‘lchash diapazoni 2 sm – 400 sm (4 m)
O‘lchash aniqligi ±3 mm
Sensor o‘lchami ~45mm x 20mm x 15mm

Diqqat: Sensor tekis va qattiq yuzalardan yaxshi aks-sado qaytaradi. So‘ruvchan (masalan, mato) yoki notekis (masalan, g‘ovak) yuzalarda natija aniq bo‘lmasligi mumkin.

How Does Bitcoin Work?

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
