The SM300 is a Door/Window Sensor that can be installed on doors, windows, cat flaps, wardrobes, drawers and any other objects that open and close. The sensor transmits open/close signals to your device when two parts of the kit are moved away or attached together. It will also transmit an alert signal in case of a low battery. The energy saving WiFi module allows a transmitting distance of 40m to the wireless router.
