Hoʻokomo ʻia ka mīkini paʻi paʻa waho i loko o ke kaʻa kaʻa a nānā pono i ke kaomi ʻana o ke kaʻa, ka mahana, a me ka pae pākaukau. ʻaʻole e hoʻopilikia ʻia ka pololei o ke ana ʻana o ke kaila. I ke ana ʻana o ka mahana wela, e loaʻa i ka sensor waho kahi hewa o 1-2 degere i hoʻohālikelike ʻia me ka mea i kūkulu ʻia.

Ke hoʻohana nei ka mea ʻike hoʻopaʻa paʻa waho i ka mea uila uila e hoʻouna i ka ʻike kaomi mai waho o ka huila i ka module hoʻokipa waena, a laila hōʻike i ka ʻikepili kaomi o kēlā me kēia huila. Ke haʻahaʻa loa ka puʻupuʻu a i ʻole ka lele ʻana o ka ea, e hoʻāla koke ka ʻōnaehana. ʻO ka ʻōnaehana transmitter nā ʻāpana aʻe: ʻāpana uila (me ka module paʻi paʻa, ka oscillator crystal, antenna, module RF, module low-frequency, pākaukau) a me ka ʻāpana hana (shell, strap).

Pākuʻi paʻi pāpaʻi: I loko o ka ʻōnaehana transmitter, ʻo ka module kaomi ʻana he module i hoʻohui nui ʻia e hoʻoili i ka MCU, ka ʻike kaomi, a me ka ʻike wela. Ma ka hoʻokomo ʻana i ka firmware i loko o ka MCU, hiki ke hōʻiliʻili ʻia ka ʻikepili, ka wela, a me ka wikiwiki e like me ia, a hoʻouna ʻia ma o ka module RF.

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

Antenna: Hiki i ka antenna ke hoʻouna i ka ʻikepili i hoʻouna ʻia e 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: Hiki i nā antenna haʻahaʻa haʻahaʻa ke pane i nā hōʻailona haʻahaʻa haʻahaʻa a hoʻouna iā lākou i MCU.

Pākuʻi: Mana i ka MCU. He hopena nui ka mana pākaukau i ke ola lawelawe o ka transmitter.

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

Shell: Hoʻokaʻawale i nā ʻāpana uila i loko mai ka wai, ka lepo, ka uila static, a me nā mea ʻē aʻe, ʻoiai e pale ana i ka hopena mechanical i nā ʻāpana kūloko.
