Nqe lus piav qhia:

Tus neeg hais lus piezoelectric yog lub suab nrov uas siv cov txiaj ntsig piezoelectric los tsim lub suab. Thawj lub tshuab hluav taws xob tau tsim los ntawm kev siv lub zog hluav taws xob rau cov khoom siv piezoelectric, thiab cov lus tsa suab no feem ntau hloov pauv mus rau hauv lub suab hnov siv diaphragms thiab resonators. Muab piv rau lwm tus neeg tsim qauv hais lus piezoelectric hais lus kuj yooj yim rau tsav; piv txwv li lawv tuaj yeem txuas ncaj qha rau TTL cov txiaj ntsig, txawm hais tias cov neeg tsav tsheb nyuaj tuaj yeem ua rau muaj suab nrov dua. Feem ntau lawv ua haujlwm tau zoo hauv thaj tsam ntawm 1 - 5kHz thiab txog li 100kHz hauv daim ntawv thov ultrasound.

Kev qhia tshwj xeeb:

  • Buzzer hom: 8 ohm, 0.5W
  • Nyob voltage: 1.5VDC
  • Rated tam sim no: tsawg dua lossis sib npaug rau 60mA
  • Cov zis: 85dB
  • Resonance zaus: 2048Hz
  • Kev khiav hauj lwm Kub: -20 txog +45 degree Celcius

Tus pin uas muaj + kos npe rau sab saum toj txuas nrog ib qho ntawm tus lej digital ntawm Arduino Uno

Lwm tus pin txuas nrog GND tus pin ntawm Arduino UNO.

Kauj ruam 3: Source Code

  1. Rub cov ntawv xeem thiab qhib nws los ntawm kev siv Arduino software lossis IDE.
  2. Nco ntsoov tias koj tau xaiv lub rooj tsav xwm raug thiab qhov chaw nres nkoj sib raug. (Hauv qhov kev qhia no, Arduino Uno tau siv)
  3. Tom qab ntawd, xa cov ntawv xeem mus rau hauv koj Arduino Uno.
