Four-in-one and human friendly design parking senor

Four-in-one and human friendly design parking senor

Specification:

Four-in-one and human friendly design parking senor, alocohol breathalyzer, electronic clock with perpetual calendar thermometer

1. 
   Parking position system will start automatically when vehicle reversing
   
2. When parking sensor start, the 4 sensors will be self tested to check whether it is on good condition or not within 2 seconds. There are five symbols, 1E,2E,3E,4E on the display corresponding A,B,C,D on the sensors. If one of the symbols on the display is shining, then the corresponding sensors must be malfunctioning.
   
3. Parking sensor will detect any obstacle within a distance of 2.5m long with accuracy of 0.01m
   
4. Parking sensor can detect human body up to 1.5m long
   
5. Human voice reminding remitted from siren when parking, like 2.0m, 1.5m,1.2m,1.0m, 0.8m, 0.6m, stop.
   
6. LCD display measured distance when parking
   
7. Three modes for optional, human voice reminding, heartbeat style voice, and mute mode.
   
8. Unique appearance design. Outstanding technology design for worst weather like raining day and dark night
   
9. Built -in installation, 360 degree rotation adjustable, electromagnetic wave resistance.
   
10. Alcohol delecting MEMS system, combined together with MEMS components and CPU
    
11. The device detects and measurcs alcohol in expired air so as to determine the concentration of alcohol in a person's blood, then a voice reminding will remits
    
12. Light sensitive. Alcohol molecule can be collected by MEMS sensor and analyzed by CPU. So then the driver will be warmly. Reminded to avoid any possible traffic accidence.
