Koj puas xav xa cov ntaub ntawv wireless? yooj yim thiab tsis muaj microcontroller xav tau?

Ntawm no peb mus, hauv cov lus qhia no kuv yuav qhia koj li yooj yim rf transmitter thiab tus txais tau npaj los siv!

Hauv cov lus qhia no koj tuaj yeem xa thiab tau txais cov ntaub ntawv siv cov khoom pheej yig heev!

Nrog kev pab ntawm peb cov phooj ywg HT12E (ENCODER) thiab HT12D (DECODER) thiab ib khub ntawm Rf modules ntawm 433 Mhz.

Kauj ruam 2: Txheej txheem cej luam

RF tus xa xov nrog thiab tus kav hlau txais xov zoo tuaj yeem xa cov ntaub ntawv mus txog 500 ft (sab nraum zoov thiab tsis muaj osbtacles)

Lub zog ua haujlwm ntawm RF transmitter yog: (3.3v - 5 v)

Lub zog ua haujlwm ntawm RF tus txais yog: (5v - 9v).

Kauj Ruam 3: Ua Transmitter

Lub zog ua haujlwm ntawm RF transmitter yog: (3.3v - 5 v)

PINOUT NTAWM HT12E (ENCODER)

Pin 1-8: Kev taw qhia ntawm tus neeg txais kev taw qhia, nws txhais tau tias nws tuaj yeem hloov pauv chaw nyob rau kev sib tham nrog tus kheej yog xav tau

9. VSS txuas nrog GND

10-13. AD hauv cov pins no yog rau xa cov ntaub ntawv ntawm 3 khoom (hauv peb kis mus rau tus txais)

14. Kev xa mus kom zoo, nws tuaj yeem ua tiav txuas tus pin no rau GND

15-16. Hauv cov chaw nres nkoj no nws yuav tsum tso "oscillation resistor" tseem ceeb heev siv tus nqi 1 M ohm

17. Tus pin no yuav tsum txuas nrog Cov ntaub ntawv tus pin ntawm peb 433 Mhz RF transmitter.

18. Tus pin no txuas nrog VCC lossis peb lub davhlau ya nyob twg zoo ntawm peb lub zog lossis lub roj teeb

Kauj Ruam 4: Ua Tus Txais

PINOUT NTAWM HT12D (DECODER)

1-8. Txuas nrog gnd kom pab tau kev sib tham nrog HT12E

9. VSS tus pin no mus rau GND.

10-13. "AD" IC siv tus pin no rau cov ntaub ntawv tso tawm uas tau xa nrog tus xa tawm, hauv peb qhov teeb meem coj los qhia qhov tau txais cov ntaub ntawv thiab tso tawm ncaj qha rau txhawm rau txuas txuas lossis lwm yam uas koj xav tau.

14. "DIN" tus pin no txuas nrog DATA ntawm peb 433 Mhz RF tus txais.

15-16. Hauv cov chaw nres nkoj no txuas nrog tus tiv thaiv nrog tus nqi ntawm 68 k ohms lossis tus nqi ze heev xws li 70 k lossis 60 k (TSEEM CEEB: Tsis txhob hloov tus nqi ntawm tus tiv thaiv no yog tias koj ua rau koj lub Circuit Court nws tsis ua haujlwm).

17. Tsis muaj kev sib txuas.

18. tus pin no mus rau VCC lossis qhov zoo ntawm peb lub zog siv.
