Kodi kusiyana pakati pa IR ndi RF ndi kotani?

Infrared ndi chidule cha IR. Ndi mtundu wa ma radiation amagetsi okhala ndi ma wavelengths omwe ndi aatali kuposa kuwala kooneka koma aafupi kuposa mafunde a wailesi. Amagwiritsidwa ntchito nthawi zambiri polankhulana opanda zingwe chifukwa zizindikiro za infrared zimatha kutumizidwa mosavuta ndikulandiridwa pogwiritsa ntchito ma IR diode. Mwachitsanzo, infrared (IR) imagwiritsidwa ntchito kwambiri powongolera kutali zida zamagetsi monga ma TV ndi ma DVD player. Ingagwiritsidwenso ntchito potenthetsera, kuumitsa, kuzindikira, ndi spectroscopy, pakati pa zinthu zina.

Mafupikitsidwe a wailesi (Radio Frequency) ndi chidule cha RF. Chimatanthauza kuchuluka kwa ma frequency amagetsi omwe nthawi zambiri amagwiritsidwa ntchito polankhulana opanda zingwe. Izi zimaphatikizapo ma frequency kuyambira 3 kHz mpaka 300 GHz. Mwa kusintha ma frequency, amplitude, ndi gawo la mafunde onyamula, zizindikiro za RF zimatha kutumiza chidziwitso patali kwambiri. Mapulogalamu ambiri amagwiritsa ntchito ukadaulo wa RF, kuphatikiza kulumikizana, kuwulutsa, machitidwe a radar, kulumikizana kwa satellite, ndi ma network opanda zingwe. Ma transmitter ndi ma receiver a wailesi, ma WiFi routers, mafoni am'manja, ndi zida za GPS zonse ndi zitsanzo za zida za RF.

Ma IR (Infrared) ndi RF (Radio Frequency) onse amagwiritsidwa ntchito kwambiri polankhulana opanda zingwe, koma pali kusiyana kwakukulu:
1. Kuchuluka kwa ma RF: Ma RF ali ndi kusiyana kwakukulu kuposa ma infrared. Ma RF transmission amatha kudutsa m'makoma, pomwe ma infrared singathe kudutsa.
2. Mzere Wowonekera: Ma transmission a infrared amafuna mzere wowonekera bwino pakati pa chotumizira ndi cholandirira, koma ma frequency a wailesi amatha kuyenda kudzera mu zotchinga.
3. Kusokoneza: Kusokoneza kwa zipangizo zina zopanda zingwe m'derali kungakhudze ma RF signals, ngakhale kuti kusokoneza kwa ma IR signals sikwachilendo.
4. Bandwidth: Popeza RF ili ndi bandwidth yayikulu kuposa IR, imatha kunyamula deta yambiri mwachangu.
5. Kugwiritsa ntchito mphamvu: Popeza IR imagwiritsa ntchito mphamvu zochepa kuposa RF, ndi yoyenera kwambiri pazida zonyamulika monga zowongolera kutali.

Mwachidule, IR ndi yabwino kwambiri polankhulana patali, pomwe RF ndi yabwino kwambiri polankhulana patali, komwe kumalowetsa zopinga.

Lumikizanani nafendipo tikhoza kugawana zambiri zokhudza magetsi a LED.
