Price from 5,20 $

Don`t laugh, dude. The key fob, as well as the sensor, operate at a radio frequency of 433 MHz. And do you think the sensor will send you an alarm message on the key fob on the VHF band?: ) The communication radius of the key fob with the sensor is 10-15 meters :) The key fob is only for setting and removing the signaling remotely and for indicating low battery. The sensor, when triggered, just yells, but you can connect it to a GSM relay or another host (W18), which will notify you of a violation.
