Kuyambitsa Mfundo Yogwirira Ntchito ya Humidity Sensor ndi Ntchito Yogwiritsa Ntchito

Kodi sensa ya chinyezi ndi chiyani?

Masensa a chinyezi angatanthauzidwe ngati zida zamagetsi zotsika mtengo zomwe zimagwiritsidwa ntchito poyeza chinyezi cha mpweya.Masensa a chinyezi amadziwikanso kuti hygrometers.Njira zoyezera chinyezi zimaphatikizapo chinyezi chapadera, chinyezi chamtheradi ndi chinyezi chochepa.Mitundu iwiri ikuluikulu ya masensa a chinyezi imagawidwa m'masensa amtheradi a chinyezi ndi masensa achibale a chinyezi.

Kutengera zinthu zomwe zimagwiritsidwa ntchito poyeza chinyezi, masensa awa amaikidwanso m'gulu la masensa a kutentha kwa kutentha, ma sensor anyezi a resistive, ndi ma capacitive humidity sensors.Zina mwa magawo poganizira masensa awa ndi nthawi yoyankha, kulondola, kudalirika, ndi mzere.

Ntchito mfundo ya chinyezi sensa

Sensa ya chinyezi ndi chipangizo chofunikira chomwe chimathandiza kuyeza chinyezi cha chilengedwe chozungulira.Nthawi zambiri, masensa amenewa amakhala ndi chigawo chimodzi chomwe chimazindikira chinyezi ndi thermistor yomwe imayesa kutentha.Mwachitsanzo, gawo la sensor capacitor ndi capacitor.Mu sensa ya chinyezi yomwe imawerengera kuchuluka kwa chinyezi, kusintha kwa chilolezo cha zinthu za dielectric kumayesedwa.

Zida zomwe zimagwiritsidwa ntchito pomanga ma sensors otsutsa zimakhala ndi resistivity yochepa.Zida zotsutsa izi zimayikidwa pamwamba pa ma electrode awiri.Pamene mtengo wa resistivity wa zinthu izi ukusintha, kusintha kwa chinyezi kumayesedwa.Ma polima ochititsa chidwi, ma electrolyte olimba, ndi mchere ndi zitsanzo za zida zolimbana ndi zomwe zimagwiritsidwa ntchito popanga zowunikira.Mtheradi chinyezi makhalidwe, Komano, amayezedwa ndi matenthedwe conductivity masensa.Tsopano tiyeni tiwone momwe sensa ya chinyezi imagwirira ntchito.

Kugwiritsa ntchito sensa ya chinyezi

Capacitive factor humidity sensors amagwiritsidwa ntchito kuyeza chinyezi mu osindikiza, makina a HVAC, makina a fax, magalimoto, malo ochitira nyengo, mafiriji, kukonza chakudya, ndi zina zambiri.Chifukwa cha kukula kwawo kochepa komanso mtengo wotsika, masensa otsutsa amagwiritsidwa ntchito kunyumba, nyumba ndi mafakitale.Thermal conductivity sensors amagwiritsidwa ntchito kwambiri mu zowumitsa, kutaya madzi m'thupi, zomera zamankhwala, etc.

Chinyezi chathu cha digito ndi sensa ya kutentha imachokera ku teknoloji ya planner capacitance yomwe imagwirizanitsa zowunikira ndi kutentha muzinthu zomveka.Pogwiritsa ntchito chidziwitso chathu chochuluka powerenga kusiyana kwa capacitance mu accelerometers ndi gyroscopes, tinapanga chinthu chosiyanitsa capacitance chomwe, chikaphatikizidwa ndi sensa ya kutentha, chimapereka chinyezi.Ndiosavuta kugwiritsa ntchito ndi sensa, makina opangira ma siginecha, ma calibration onboard ndi ma aligorivimu ogwirizana omwe amaphatikizidwa mu phukusi limodzi.

Kukula kwakung'ono komanso kugwiritsa ntchito mphamvu pang'ono ndikoyenera kugwiritsa ntchito mafoni ogula, nyumba zanzeru (zida zam'nyumba ndi HVAC), ndikusungirako ndikugwiritsa ntchito.
