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 recent times, Telegram has gained a lot of popularity because of the controversy over WhatsApp’s new privacy policy. In January 2021, Telegram was the most downloaded app worldwide and crossed 500 million monthly active users. And with so many active users on the app, people might get messages in bulk from a group or a channel that can be a little irritating. So to get rid of the same, you can mute groups, chats, and channels on Telegram just like WhatsApp. You can mute notifications for one hour, eight hours, or two days, or you can disable notifications forever.
How to Invest in Bitcoin?
Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
