Hav guys, Kuv rov qab los nrog txhua yam qhia tshiab. Cia peb pib.

RF Beacon yog dab tsi?

Ib lub teeb liab RF yog cov cuab yeej siv wireless uas hais txog qhov chaw ruaj khov thiab tso cai rau cov khoom siv nrhiav pom kom pom nws. Nws xa cov xov tooj cua txuas mus los lossis ib ntus nrog cov ntaub ntawv txwv - piv txwv li, nws tus cim lossis chaw nyob - ntawm cov xov tooj cua tshwj xeeb, uas tau khaws los ntawm kev taw qhia -nrhiav tshuab ntawm nkoj, dav hlau, thiab tsheb los txiav txim qhov chaw ntawm lub cuab yeej. Qee zaum, lub teeb nyem ua haujlwm tau ua ke nrog qee qhov kev sib kis, xws li cov ntaub ntawv xov tooj cua lossis xov xwm huab cua.

Kauj Ruam 1: Cov Ntaub Ntawv Yuav Tsum Tau

  • 1k ohm resistor (R5 R6 R7)
  • 10K ohm resistor (R1 R3 R4 R8)
  • 100K ohm resistor (R2)
  • 10nF capacitor (C2 C3 C4)
  • 10uf capacitor (C1)
  • 2N3904 (Q1 Q2)
  • 555 lub sijhawm (IC1, IC2)
  • RF module (433 MHz)

Kauj ruam 3: Ua haujlwm

RF beacon muaj peb ntu tseem ceeb; Qhov tsawg zaus 555 oscillators, suab (ntau zaus) oscillator, thiab RF 433MHz module.

Thawj chav, tus oscillator qis zaus, tsim cov mem tes ntawm qhov zaus ntawm kwv yees li 1Hz uas muaj lub voj voog ua haujlwm loj heev (ze rau 99.9%). Lub teeb liab no yog tom qab ua tsaug rau Q1 hauv daim ntawv ntawm TSIS lub qhov rooj, qhov no tsim cov mem tes nrog lub voj voog ua haujlwm ze 0.01%.

Kev ua haujlwm qis hauv lub plawv dhia tau txuas nrog RESET ntawm lub suab 555 oscillator. Thaum cov zis los ntawm qib qis oscillator theem (tom qab Q1) dhau los 0V, lub suab oscillator (IC2), yog neeg xiam oob khab thiab qhov tshwm sim tsis muaj lub suab teeb tsa tau tsim. Thaum cov zis ntawm qhov qis zaus oscillator dhau los ua VCC ces lub suab oscillator (IC2) tau qhib thiab tsim lub suab muaj peev xwm. Lub teeb liab no tau hloov pauv thiab tom qab ntawd pub rau hauv RF module uas tso lub suab nrov ntawm 433MHz spectrum uas tuaj yeem khaws tau yooj yim los ntawm cov txais.

Kuv tau xa cov ntaub ntawv Gerber rau LIONCIRCUITS

Feem ntau ntawm kuv cov neeg nyeem yuav tsum paub kuv pom zoo lawv vim tias lawv tus nqi pheej yig thiab cov kev pabcuam zoo li kev tshuaj xyuas DFM tam sim.

Mus ntsib lawv Cov Kev Pabcuam nplooj ntawv kom paub ntau ntxiv txog lawv.

Okay, cov neeg. Kuv tuaj yeem faib cov ntaub ntawv Gerber ib yam yog tias leej twg xav tau. Xav tias dawb.
