Re thabetse ho hlahisa sehlahisoa sa rona ka ho lekola khatello ea mabili - sensor ea kantle ea khatello ea mabili e kentsoeng setsing sa lebili la koloi. Sensor ena e hlokomela ka bo eona khatello ea mabili, mocheso le tefiso ea betri ho netefatsa ts'ebetso e nepahetseng le polokeho ea 'mileng.

Sistimi ea transmitter e na le likarolo tse latelang: Karolo ea elektroniki (ho kenyeletsoa mochini oa khatello ea mabili, kristale oscillator, antenna, module ea RF, module ea low-frequency, betri) le Karolo ea Meaho (khetla, strap).

Mojule oa khatello ea Tire: Mojule oa khatello ea Tire: Ena ke mojule o kopantsoeng haholo oa khatello ea thaere o ruang karolo ea microcontroller (MCU), sensor ea khatello, le sensor ea mocheso. Ka ho kenya firmware ho MCU, e ka bokella khatello, mocheso, le data ea ho potlakisa, 'me ea li sebetsa le ho li romela ka module ea RF.

Crystal oscillator: Oscillator ea kristale e fana ka oache ea kantle bakeng sa MCU, 'me ka ho hlophisa lirejisete tsa MCU, maqhubu a bohareng le litekanyetso tsa sekhahla sa lets'oao la RF le rometsoeng ke transmitter li ka khethoa.

Antenna: Antenna e khona ho fetisa data ho tsoa ho MCU.

Mojule oa maqhubu a seea-le-moea: Lintlha li nkiloe mochining oa khatello ea mabili 'me li rometsoe ka maqhubu a seea-le-moea a 433.92MHZFSK.

Antenna e tlase ea maqhubu: Antenna ea maqhubu a tlase e arabela mats'oao a maqhubu a tlase ebe e a fetisetsa ho MCU.

Betri: Boemo ba betri bo na le tšusumetso e kholo bophelong ba transmitter ha o fana ka matla ho MCU.

PCB: Likarolo tse tsitsitseng le ho fana ka likhokahano tse tšepahalang tsa motlakase.

Shell: E arola likarolo tsa elektronike tse ka hare ho metsi, lerōle, motlakase o tsitsitseng, joalo-joalo, 'me ka nako e ts'oanang e thibela likarolo tsa ka hare ho ts'usumetso e tobileng ea mochine.
