Kodi pali kusiyana kotani pakati pa IR ndi RF?

Infrared imafupikitsidwa ngati IR. Ndi mtundu wa ma radiation a electromagnetic okhala ndi kutalika kwa mafunde omwe ndiatali kuposa kuwala kowoneka koma kocheperako kuposa mafunde a wailesi. Imagwiritsidwa ntchito pafupipafupi polumikizirana opanda zingwe chifukwa ma infrared siginecha amatha kuperekedwa ndikulandiridwa mosavuta pogwiritsa ntchito ma diode a IR. Mwachitsanzo, infrared (IR) imagwiritsidwa ntchito kwambiri poyang'anira zida zamagetsi monga ma TV ndi ma DVD player. Itha kugwiritsidwanso ntchito kutenthetsa, kuyanika, kuzindikira, ndi spectroscopy, mwa zina.

Radio Frequency imafupikitsidwa ngati RF. Zimatanthawuza kusiyanasiyana kwa ma frequency a electromagnetic omwe amagwiritsidwa ntchito polumikizira opanda zingwe. Izi zimaphatikiza ma frequency kuchokera ku 3 kHz mpaka 300 GHz. Posintha ma frequency, matalikidwe, ndi gawo la mafunde onyamulira, ma siginecha a RF amatha kunyamula zidziwitso mtunda wautali. Mapulogalamu ambiri amagwiritsa ntchito ukadaulo wa RF, kuphatikiza kulumikizana ndi matelefoni, kuwulutsa, makina a radar, mauthenga a satana, ndi maukonde opanda zingwe. Mawayilesi ndi zolandila, ma router a WiFi, mafoni am'manja, ndi zida za GPS zonse ndi zitsanzo za zida za RF.

Onse IR (Infrared) ndi RF (Radio Frequency) amagwiritsidwa ntchito kwambiri polumikizira opanda zingwe, koma pali kusiyana kwakukulu:
1. Range: RF ili ndi mitundu yayikulu kuposa infuraredi. Kutumiza kwa RF kumatha kudutsa makoma, pomwe ma siginecha a infrared sangathe.
2. Mzere wa mawonekedwe: Kutumiza kwa infrared kumafuna mzere wowonekera bwino pakati pa chowulutsira ndi cholandila, koma ma siginecha a mawayilesi amatha kudutsa zopinga.
3. Kusokoneza: Kusokoneza kwa zipangizo zina zopanda zingwe m'derali kungakhudze ma siginecha a RF, ngakhale kusokonezedwa ndi ma siginecha a IR sikwachilendo.
4. Bandwidth: Chifukwa RF ili ndi bandwidth yayikulu kuposa IR, imatha kunyamula zambiri mwachangu.
5. Kugwiritsa ntchito mphamvu: Chifukwa IR imagwiritsa ntchito mphamvu zochepa kuposa RF, ndiyoyenerera bwino zipangizo zonyamula katundu monga zowongolera zakutali.

Mwachidule, IR ndiyopambana pakuyankhulirana kwakanthawi kochepa, kowoneka bwino, pomwe RF ndiyabwino pakulankhulana kwautali, wolepheretsa kulumikizana.

Lumikizanani nafendipo titha kugawana zambiri za magetsi amtundu wa LED.
