Electromagnetic parking sensor system

LED display electromagnetic parking sensor                                                              
FUNCTIONS                                                                                              
LED display electromagnetic parking sensor detects obstacles behind the car according to the reflection principle of electromagnetic wave, the system comprises of an electronic box, an antenna sensor and a buzzer or display.                                                                                                  FEATRUES:· Indicate the distance of obstacles behind your cars by different frequency beeping.               
· The sensor antenna is installed inside the bumper, no need for drill on the bumper.                 
· Easy installation, totally built-in mounting with no bad effect to the car appearance.                    
· Detection in all directions without dead angle.                                                           
· During approaching to an obstacle, the electronic unit activates the acoustic signal with types of Beeping.     
1)  A continuous sound of “BEEP” approximately between 0-0.3m2)                                                                          
A short interval sound of “BEEP” approximately between 0.3-0.5m3)                                                               
A long interval sound of “BEEP” approximately between 0.5-0.7m                                                                       

TECHNICAL CHARACTERISTICS.                                                                                         
·Working voltage: DC12V 2V
