Good Day, if possible i would like to ask for some advice concerning the gravity digital microwave sensor. I am busy with a project where we have to detect movement and minimal sound at a 20m. With regards to the gravity sensor i see a maximum distance of 16m is there a possibility of another kind of sensor that can detect movement at say 20m or would it be possible to increase the distance if i use a small dish. The whole system must be stand alone with no pc connected to it only a buzzer, can you please supply me with a pats list to build this system.
Thanks
Mike
