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.

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
