Inquiry (采购产品): Special Device I am not an electronics tech, I am a mechanic. So if I do not get the specific terminology correct please overlook. I am attempting to build a device that requires a very small, low battery demand transmitter which will actuate a relay when placed within a certain proximity of that relay. It would be preferable for the acutating distance to be adjustable. IR will not work as I require there be no need for a line of sight to actuate the relay. Do you have any such equipement or can you suggest a source? Thank You for your assistance.
