Chii chinosiyanisa IR neRF?

Infrared inopfupikiswa seIR. Imhando yemwaranzi yemagetsi ine marefu ewavelength akareba kupfuura chiedza chinoonekwa asi mapfupi pane mawave eredhiyo. Inowanzoshandiswa pakutaurirana pasina waya nekuti masaini einfrared anogona kutumirwa uye kugamuchirwa zviri nyore uchishandisa maIR diodes. Semuenzaniso, infrared (IR) inoshandiswa zvakanyanya pakudzora zviri kure michina yemagetsi yakaita sematerevhizheni nemaDVD players. Inogona zvakare kushandiswa pakudziisa, kuomesa, kunzwa, uye spectroscopy, pakati pezvimwe zvinhu.

Mafrequency eRadio akapfupikiswa seRF. Anoreva huwandu hwemafrequency emagetsi anowanzo shandiswa pakutaurirana pasina waya. Izvi zvinofukidza mafrequency anotangira pa3 kHz kusvika 300 GHz. Nekuchinja mafrequency, amplitude, uye phase ye carrier wave, masaini eRF anogona kutakura ruzivo munzvimbo dzakakura. Mapurogiramu mazhinji anoshandisa tekinoroji yeRF, kusanganisira telecommunications, broadcasting, radar systems, satellite communications, uye wireless networking. Ma radio transmitters ne receivers, WiFi routers, mobile phones, uye GPS gadgets zvese mienzaniso yeRF equipment.

IR (Infrared) neRF (Radio Frequency) zvese zvinoshandiswa zvakanyanya pakutaurirana pasina waya, asi pane misiyano mikuru:
1. Range: RF ine range yakakura kupfuura infrared. RF transmissions inogona kupfuura nepamadziro, asi masaini e infrared haagone.
2. Mutsetse wekuona: Matransmitter einfrared anoda kuti pave nemutsetse wakajeka wekuona pakati petransmitter nereceiver, asi masaini eredhiyo anogona kuyerera nepazvipingamupinyi.
3. Kupindira: Kupindira kwemamwe mawaya asina waya munharaunda iyi kunogona kukanganisa masaini eRF, kunyange hazvo kupindira kwemasaini eIR kusingawanzoitiki.
4. Bandwidth: Nekuti RF ine bandwidth yakakura kupfuura IR, inogona kutakura data rakawanda nekukurumidza.
5. Kushandiswa kwesimba: Nekuti IR inoshandisa simba shoma pane RF, yakakodzera zvirinani kune zvishandiso zvinotakurika zvakaita seremote controls.

Muchidimbu, IR iri nani pakutaurirana kuri kure, kusingaonekwi, nepo RF iri nani pakutaurirana kuri kure, kusingapindi zvipingamupinyi.

Taura nesuuye tinogona kugovera rumwe ruzivo nezvemwenje ye LED strip.
