using a simple IR sensor is the simplest of all.But you need to consider a lot of things like the distance range which u want to detect and the lighting condition you have.circuit would be simple one.you just have to use a ir sensor(use simple LED detector pair for rs.20 or use good sharp sensors) and a comparator(like LM339).programming ur microcontroller for a stuff like this would reqire a one or two lines of code.Like
if(pin connected to sensor is high)
{send alarm;}
thats all..
