Handheld Vehicle Lock Control System Using Wireless Communication (IR / RF) Monday, February 20th, 2012  »  Posted By  »  Total 7 Comments

ABSTRACT: In this project we are using IR communication to implement the handheld vehicle lock control system. Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light (400-700 nm), but shorter than that of terahertz radiation (1 µm – 1mm) and microwaves (~30,000 µm). Infrared radiation spans roughly three orders [...]
