Digital DS18B20 Sensor Yubushyuhe Kubinyabiziga
DS18B20 nibisanzwe bikoreshwa murwego rwo hejuru rushobora gupima ubushyuhe bwa bisi. Ifite ibiranga ubunini buto, igiciro gito cyibikoresho, ubushobozi bukomeye bwo kurwanya-kwivanga kandi neza.
Iyi sensor ya DS18B20 ifata chip ya DS18B20 nkibyingenzi byo gupima ubushyuhe, ubushyuhe bwakazi ni -55 ℃～ + 105 ℃. Gutandukana bizaba ± 0.5 ℃ ku bushyuhe bwa -10 ℃～ + 80 ℃. -
Sensor ya Digitale yubushyuhe bwa Boiler, Icyumba gisukuye nicyumba cyimashini
Ibimenyetso bya DS18B20 birahagaze kandi ntibishobora guhuza intera ndende. Irakwiriye intera ndende-yubushyuhe bwo kumenya. Ibisubizo byo gupima byoherezwa muburyo bwa 9-12-biti ya digitale. Ifite ibiranga imikorere ihamye, ubuzima bwa serivisi ndende, nubushobozi bukomeye bwo kurwanya kwivanga.

Ibikoresho bikonje bikonje Kugenzura Ubushyuhe
Ubushyuhe bwa DS18B20 bukoresha chip ya DS18B20, ifite ubushyuhe bwakazi bwa -55 ° C kugeza kuri + 105 ° C, ubushyuhe bwa dogere -10 ° C kugeza + 80 ° C, n'ikosa rya 0.5 ° C; ikozwe muburyo butatu bwa shitingi ya wire kandi irapakirwa hakoreshejwe epoxy resin parfusion.

DS18B20 sensor yubushyuhe bwamazi
DS18B20 Amazi adakoreshwa na Digital Temperature Sensor ni ubwoko bwubushyuhe bugenewe gupima ubushyuhe mubikorwa bitandukanye nka HVAC, gukonjesha, no gukurikirana ikirere. Rukuruzi irashobora gutanga ubushyuhe nyabwo mubuso bwagutse (-55 ° C kugeza kuri + 125 ° C) kandi ifite imiterere ya 0.0625 ° C. Ifite icyuma kitagira amazi gitanga uburinzi ku butumburuke, bigatuma gikoreshwa hanze.

DS18B20 Sensor Ubushyuhe bwa Ventilator
DS18B20 ntisaba imbaraga ziva hanze kugirango zikore. Igikoresho gikoreshwa mugihe umurongo wamakuru DQ ari muremure. Imashini yimbere (Spp) yishyuza iyo bisi ikururwa hejuru, na capacitori igaha igikoresho mugihe bisi ikururwa hasi. "Imbaraga za parasitike" nijambo rikoreshwa mugusobanura ubu buryo bwa bisi ya bisi ikoresha amashanyarazi.

1-Umuyoboro wa bisi Porotokole Ubushyuhe bwa Sensor Kuri Inganda Zimashini
Porotokole ya 1-Wire, ikoreshwa na DS18B20, ikeneye gusa ikimenyetso kimwe cyo kugenzura itumanaho. Kugirango wirinde icyambu cya bisi kiri muri leta 3 cyangwa imiterere-y-impedance nyinshi, umurongo wikimenyetso cyo kugenzura ukenera gukanguka gukurura (umurongo wa signal ya DQ uri kuri DS18B20). Microcontroller (igikoresho cyibanze) muriyi sisitemu ya bisi imenya ibikoresho bya bisi nimero zabo 64-biti. Bisi irashobora gushyigikira umubare wibikoresho bitagira umupaka kuko buri kimwe gifite numero yihariye.

Ubushyuhe bwa Digital Sensor ya Cold -Chain Sisitemu Granary na Wine Cellar
DS18B20 ni icyuma gikoresha ubushyuhe bwa digitale izwi cyane hamwe nibiranga ubunini buto, ibyuma bito bito hejuru, imbaraga zikomeye zo kurwanya interineti, hamwe nibisobanuro bihanitse. Isohora ibimenyetso bya digitale. DS18B20 ibyuma byubushyuhe bwa digitale biroroshye kurigata kandi bipakiwe muburyo butandukanye, harimo umuyoboro, screw, magnet adsorption, ibyuma bitagira umwanda, hamwe nuburyo bwinshi bwo kwerekana.

Ubushyuhe bwa Greenhouse
Ubushyuhe bwo gusoma buva kuri sensor ya DS18B20 ni 9-bit (binary), byerekana ko amakuru yubushyuhe bwigikoresho yoherejwe kuri sensor yubushyuhe bwa DS18B20 akoresheje umurongo umwe cyangwa ko yoherejwe kuva sensor ya DS18B20. Nkigisubizo, umurongo umwe gusa (wongeyeho ubutaka) urasabwa guhuza CPU yakiriye na sensor ya DS18B20, kandi umurongo wamakuru ubwawo urashobora gukora nkisoko yingufu za sensor mu mwanya wimbaraga zituruka hanze.
