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 to Use Bitcoin?
n the U.S. people generally use Bitcoin as an alternative investment, helping diversify a portfolio apart from stocks and bonds. You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. Big companies that accept Bitcoin include Overstock, AT&T and Twitch. You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
