DS18B20 ʻikena wela kikohoʻe

Hoʻohana ka sensor wela o DS18B20 i ka chip DS18B20, ʻo ka pae wela o ka hana he -55 ℃ ~ + 105 ℃, ka pololei o ka mahana mai -10 ℃ ～ + 80 ℃, ka hewa he ± 0.5 ℃, ua hana ʻia ka pūpū i 304 meaʻai-grade stainless steel tube, a ua hana ʻia ia me ʻekolu-core, sheathed wire Conductor.
Paʻa ka hōʻailona hoʻopuka DS18B20, mamao loa ka mamao o ka hoʻouna ʻana mai ka attenuation, kūpono no ka ʻike ʻana i ka wela o nā helu he nui, ua hoʻouna ʻia nā hopena ana i nā helu 9 ~ 12, me ka hana paʻa, ke ola lawelawe lōʻihi, Ka ikaika anti-interference.

ʻO ke kaʻina hana hoʻokele o DS18B20 e hilinaʻi nui i ka ʻōnaehana kaʻa 1-Wire. Hiki i kēia ʻōnaehana kaʻa kaʻa ke hoʻomalu i hoʻokahi a ʻoi aku paha nā mea kauā me hoʻokahi mea haku kaʻa. ʻO kā mākou MCU ka mea haku, a ʻo DS18B20 mau ke kauā. ʻO nā mea kauā a pau ma ka ʻōnaehana kaʻa 1-Wire ʻO ka hoʻouna ʻana i ke kauoha a i ʻole ka ʻikepili ma muli o ke kumu o ka hoʻouna ʻana i ka bit haʻahaʻa ma mua.

ʻO ka ʻōnaehana kaʻa kaʻa 1-Wire hoʻokahi wale nō laina ʻikepili a koi i kahi pale huki huki waho ma kahi o 5kΩ, no laila ke kiʻekiʻe ka laina ʻikepili i ka wā ʻole. Hoʻopili ʻia kēlā me kēia mea hana (master a i ʻole ke kauā) i ka laina ʻikepili ma o kahi pine puka hāmama a i ʻole 3-mokuʻāina. ʻAe kēia i kēlā me kēia hāmeʻa e "hoʻokuʻu" i ka laina ʻikepili, a hiki i nā mea hana ʻē aʻe ke hoʻohana pono i ka laina ʻikepili ke hoʻouna ʻole ʻia ka ʻikepili.
