Nov yog qhov piv txwv ntawm yuav ua li cas thiaj ua kom muaj kev ruaj ntseg wireless (chav nres tsheb) nyob deb.

Feem ntau cov kev ceeb toom muaj cov txheej txheem kev ruaj ntseg, uas tuaj yeem hla dhau los ntawm txhua tus tub sab siab.

Cov kab ke nyob deb no tso siab rau siv tus lej 16 byte, yog li nyiag nkag mus nws yuav yog lub sijhawm ntawm ib qho ntawm

3, 4028236692093846346337460743177e+38 (256^16)

Nws ua haujlwm li cas:

1. Tej thaj chaw deb xa kev thov rau lub kaw lus

2. System tsim cov lej tsis raug thiab xa nws mus rau tej thaj chaw deb

3. Tej thaj chaw deb encrypts tus lej uas siv tus yuam sij tshwj xeeb thiab xa rov qab mus rau qhov system

4. Qhov kev txiav txim siab tau txais cov cai siv tus lej ib yam thiab tshawb xyuas yog tias nws sib xws nws tau tsim cov cai.

5. …

Rau lub pob Kuv siv TTP223 kov lub sensor

Khoom siv

Qhov yuav tsum tau ua - 2 NRF24L01 wireless tranceivers, ob lub arduinos, 2.54mm cables, khawm (DUE yuav tsis ua haujlwm)

Kauj Ruam 1: Txuas NRF24's

Serial monitor print '1' txhua zaus kuv nias lub pob - qhov ntawd txhais tau tias kev txuas tau ruaj ntseg thiab cov ntaub ntawv tau muab zais kom raug.
