Nau'in Maɗauri Sensor Matsayin Taya (Mai watsawa)

Bayani

Mun yi farin cikin gabatar da samfurin mu a cikin lura da matsa lamba na taya - firikwensin matsa lamba na waje wanda aka ɗora akan cibiyar dabaran motar. Wannan firikwensin yana lura da matsa lamba ta atomatik, zafin jiki da cajin baturi don tabbatar da ingantaccen aiki da amincin hanya.

Tsarin watsawa ya ƙunshi abubuwa masu zuwa: Sashe na lantarki (ciki har da ma'aunin matsin taya, crystal oscillator, eriya, RF module, ƙananan mitar module, baturi) da Sashe na gine-gine (harsashi, madauri).

Modulu na matsa lamba na taya: Modulun matsa lamba na taya: Wannan babban haɗe-haɗe ne na firikwensin matsi na taya wanda ya gaji naúrar microcontroller (MCU), firikwensin matsa lamba, da firikwensin zafin jiki. Ta hanyar shigar da firmware a cikin MCU, zai iya tattara matsa lamba, zafin jiki, da bayanan hanzari, da aiwatarwa da aika su ta tsarin RF.

Crystal oscillator: Crystal oscillator yana ba da agogo na waje don MCU, kuma ta hanyar daidaita rajistar MCU, ana iya tantance mitar tsakiya da siginar baud na siginar RF da mai watsawa ya aiko.

Eriya: Eriya tana iya watsa bayanai daga MCU.

Modulun mitar rediyo: An ɗauko bayanai daga tsarin matsi na taya kuma an aika ta mitar rediyo 433.92MHZFSK.

Ƙananan eriya: Ƙarƙashin eriya mai ƙararrawa yana amsawa zuwa ƙananan sigina kuma yana watsa su zuwa MCU.

Baturi: Matsayin baturi yana da tasiri mai mahimmanci akan tsawon rayuwar mai watsawa yayin samar da wuta ga MCU.

PCB: Kafaffen abubuwan da aka gyara da kuma samar da amintattun hanyoyin haɗin lantarki.

Shell: Yana keɓance kayan lantarki na ciki daga ruwa, ƙura, wutar lantarki, da sauransu, kuma a lokaci guda yana hana abubuwan ciki daga tasirin injin kai tsaye.
