Тема: LPG tank trailers
Hello,
I have a project of twenty gas tank trailers on which we must make an alarm. Tanks have something like a cabinet from where they are filled and emptied, we have to make alarm on door of the cabinet.
The customer wants no electricity to run on our installation.Because they transport LPG and is easily flammable.
Is it possible for an GPS to detect interruption of the chain if we connect negative power(ground) Into magnetic sensor.
Can anyone help with this case?
