Wireless Door/Window Sensor EWD3
EWD3 is designed to protect doors, windows, or even drawers. It senses opening and vibration to inform a user if they attempt to break in happens and measures home temperature.

Innovative Eldes wireless technology enables users to reach an impressive up to 3 km range in open areas. You will not need to change the batteries every few months – EWD3 contains amazing up to 5-year battery life!

EWD3 is designed to expand the security system’s capabilities and protect entrances 24/7. An integrated shock sensor warns the user about attempting to break a door or a window. Adjustable vibration sensitivity won’t let your noisy neighbors trigger the alarm. EWD3 can be used for home automation, e.g. the system can turn off the heating while windows are opened!
