Its made of plastic and electronic chips.This is connected to engine control unit.
The radio frequency sensor is based on the reception of electromagnetic waves.
RF-sensor in the cars are limited the channel which contain UHF electromagnetic radiation with thw exeption of the radar.
The radar(radio detection and ranging) is a system of measurement of distance and speed using radio waves.these devices have an effective range of aproximately 120m and detection angle of aproximately 4ยช.
With radar can also determine the relative speed between the own vehicle and obstacle he has in the front.
We have the following example of the sensores based on RF.
-The tyre pressure sensor.
-Remote control for opening and closing doors.
-Comunication with bluetooth devices,which allow to exchanging data,music images with mobile phone,etc..
