hi, i have a project that needs to detect the speed of a vehicle and once the vehicle exceeds a certain speed (ex. 30kph) a gsm module will send a message to someone.
can you please give me an advice to what microcontroller and sensor to use?
thank you in advance.
 

we can design using simple micro-controller like 8051 and photo transistor.
check this it may be useful.

You can keep it simple by using arduino micro-controller and sensor as ultrasonic sensor.
Interfacing of GSM and ultrasonic sensor is very simple in arduino.

Click to expand...

Very simplest method is using 8051, well supported but you shdnt expect high quality of operation...
Using pic 16F controllers will be reliable and also well supported....... You have to choose a well supported package as a beginner**
 

You should use the processor for which you can get the best hardware (e.g. development board) and software support.

I don't think that ultrasonic will give a suitable on-board vehicle speed measurement. I presume, everyone will see why when thinking about it a bit. First choice would be tachometer pulse counting, if available. GSM module with GPS might be an elegant option.
 

As FvM said tachometer is a best suitable option and you can create one yourself.search the forum related threads.
