HC-SR04 Ping distance sensor

Working on a small mockup that should read sensors, [do some stuff here] and send it to clients website/server..

Using a sensor like the HC-SRo4 Ping distanse sensor to send a signal to the RasBotPi when someone walks inside the range is a nice idea for the moment. Although for the project I am working on, this is not the best idea 🙂

But Arduino and a breadboard gives you the power to fool arround and see if it fits your needs.

On twitter I found out about this guy: Hazim Bitar.
His website is http://www.techbitar.com and you can follow him on twitter too.  He created an app that reads Arduino sensors using bluetooth. Got me thinking about the final project and how we can overcome the distance without the needs of cable (or to setup a complete wifi network) on the “moving” location.

Anyway, this sensor came from china (dx.com). There are lots of sketches to find if you do a  google. The one I post here works too. Dunno exact where I found it..
