Human tracking has been a very active research topic in the last few years due to its growing importance in security. In Our Project we use a Bluetooth tracking device which helps in detecting the children with the help of frequency ranges of the main router. Once the children have been detected they are tracked by employing frequency selection within the router.

Using water proof ultra Sonic sensor we can detect the obstacles present under the water to avoid road accidents which are happening due to collision with big obstacles like rocks, icebergs, etc..
