Ua hauʻoli mākou i ka hoʻolauna ʻana i kā mākou huahana i ka nānā ʻana i ka puʻu pila - ʻo ka mea ʻike puʻupuʻu o waho i kau ʻia ma ka huila o ke kaʻa. Mālama pono kēia sensor i ke kaomi pilahi, ka mahana a me ka uku pākaukau e hōʻoia i ka hana maikaʻi loa a me ka palekana o ke alanui.

Aia ka ʻōnaehana transmitter i nā ʻāpana aʻe: ʻĀpana uila (me ka module kaomi paʻa, ka oscillator kristal, antenna, module RF, module haʻahaʻa haʻahaʻa, pākaukau) a me Architecture Part (shell, strap).

Pākuʻi kaʻa kaʻa: ʻO kēia ka mea i hoʻohui pū ʻia i ka mīkini paʻi paʻi paʻa i hoʻoili ʻia i ka ʻāpana microcontroller (MCU), ʻike kaomi, a me ka ʻike wela. Ma ka hoʻokomo ʻana i ka firmware i loko o ka MCU, hiki iā ia ke hōʻiliʻili i ke kaomi, ka mahana, a me ka ʻikepili wikiwiki, a hana a hoʻouna iā lākou ma o ka module RF.

Crystal oscillator: Hāʻawi ka oscillator kristal i ka uaki waho no ka MCU, a ma ka hoʻonohonoho ʻana i nā papa inoa o ka MCU, hiki ke hoʻoholo ʻia ke kikowaena waena a me nā ʻāpana baud rate o ka hōʻailona RF i hoʻouna ʻia e ka transmitter.

Antenna: Hiki i ka antenna ke hoʻouna i ka ʻikepili mai ka MCU.

Lekiō uila: Ua lawe ʻia ka ʻikepili mai ka module kaomi a hoʻouna ʻia ma o ka lekiō 433.92MHZFSK.

Antenna haʻahaʻa haʻahaʻa: pane ka antenna haʻahaʻa haʻahaʻa i nā hōʻailona haʻahaʻa haʻahaʻa a hoʻouna iā lākou i ka MCU.

Pākuʻi: He hopena koʻikoʻi ka pae pākaukau i ke ola o ka transmitter i ka wā e hāʻawi ai i ka mana i ka MCU.

PCB: Nā ʻāpana paʻa a hāʻawi i nā pili uila hilinaʻi.

Shell: Hoʻokaʻawale ia i nā mea uila i loko mai ka wai, ka lepo, ka uila static, a me nā mea ʻē aʻe, a ma ka manawa like e pale ai i nā ʻāpana kūloko mai ka hopena mechanical.
