SHT15 Ubushyuhe n'ubushuhe

Ibisobanuro bigufi:

SHT1x yumubyigano wa digitale ni sensor igaruka. Urukurikirane rwa SHT1x rugizwe na verisiyo ihendutse hamwe na sensor ya SHT10 yubushyuhe, verisiyo isanzwe hamwe na SHT11 yubushuhe, hamwe na verisiyo yohejuru hamwe na sensor ya SHT15. Bahinduwe neza kandi batanga ibisohoka muburyo bwa digitale.

SHT15 Ubushyuhe bwa Digital-Ubushuhe sensor ± 2%）

Ubushuhe bwa sensoriste ihuza ibice bya sensor hiyongereyeho gutunganya ibimenyetso kumurongo muto kandi bigatanga ibisohoka byuzuye bya digitale.
Ikintu cyihariye cya capacitive sensor ikoreshwa mugupima ubushuhe bugereranije, mugihe ubushyuhe bupimwa na bande-icyuho. Ikoranabuhanga rya CMOSens® ryizeza ubwizerwe buhebuje nigihe kirekire.
Ibyuma bifata ibyuma bifatanye neza hamwe na 14-bit-bigereranywa-na-bihinduranya na sisitemu ya interineti. Ibi bivamo ubuziranenge bwibimenyetso, igihe cyihuse cyo gusubiza, no kutumva imvururu zo hanze (EMC).

Ihame ry'akazi SHT15:

Chip igizwe nubushobozi bwa polymer nubushuhe bworoshye nibintu byubushyuhe bukabije bikozwe mubintu bitandukanya ingufu. Ibintu byombi byunvikana bihindura ubuhehere nubushyuhe mubimenyetso byamashanyarazi, byabanje kongerwamo imbaraga nimbaraga zongera imbaraga, hanyuma na 14-bit A / D ihindura, hanyuma amaherezo ikoresheje insinga ebyiri zikoreshwa muburyo bwa digitale kugirango zisohore ikimenyetso cya digitale.

SHT15 ihindurwamo ubushyuhe buri gihe cyangwa ubushyuhe burigihe mbere yo kuva muruganda. Calibration coefficients ibitswe mubitabo byabigenewe, bihita bihindura ibimenyetso biva kuri sensor mugihe cyo gupima.

Mubyongeyeho, SHT15 ifite ibintu 1 byo gushyushya byinjijwe imbere, bishobora kongera ubushyuhe bwa SHT15 kuri 5 ° C mugihe ibintu byo gushyushya bifunguye, mugihe amashanyarazi nayo yiyongera. Intego nyamukuru yiyi mikorere nukugereranya ubushyuhe nubushuhe agaciro mbere na nyuma yo gushyushya.

Imikorere yibice bibiri bya sensor irashobora kugenzurwa hamwe. Mubushuhe bwinshi (> 95% RH) ibidukikije, gushyushya sensor birinda sensor sensor mugihe ugabanya igihe cyo gusubiza no kunoza neza. Nyuma yo gushyushya SHT15 ubushyuhe buriyongera kandi nubushyuhe bugereranije buragabanuka, bikavamo itandukaniro rito mubiciro byapimwe ugereranije na mbere yo gushyushya.

Imikorere ibipimo bya SHT15 nibi bikurikira:

1) Ikigereranyo cyo gupima ubuhehere: 0 kugeza 100% RH;
2) Ikigereranyo cyo gupima ubushyuhe: -40 kugeza + 123.8 ° C;
3) Ibipimo byo gupima ubuhehere: ± 2.0% RH;
4) Ibipimo byo gupima ubushyuhe: ± 0.3 ° C;
5) Igihe cyo gusubiza: 8 s (tau63%);
6) Kurohama byuzuye.

SHT15 Ibiranga imikorere ：

SHT15 ni ubushyuhe bwa digitale hamwe nubushuhe bwa sensor chip kuva Sensirion, Busuwisi. Chip ikoreshwa cyane muri HVAC, ibinyabiziga, ibikoresho bya elegitoroniki, kugenzura byikora nizindi nzego. Ibintu nyamukuru biranga ni ibi bikurikira:

1) Kwinjiza ubushyuhe nubushyuhe bwo kumva, guhindura ibimenyetso, guhindura A / D hamwe na bisi ya I2C muri chip imwe;
)
3) Gahunda yo guhindura gahunda yo gupima neza kandi yubatswe muri A / D ihindura;
4) Gutanga indishyi zubushyuhe hamwe nubushuhe bwo gupima nubushuhe bwo murwego rwohejuru rwo kubara ikime;
5) Irashobora kwibizwa mumazi yo gupimwa kubera tekinoroji ya CMOSensTM.
