DWS-RF01
DWS-RF01 is one sensor option of smart home RF series, it uses a magnetic reed switch principal that reed switch inside is either close or open when the magnet is contacting or disconnecting, then to encode based on its ON /OFF state and transmit it to the Gateway via 2.4GHZ RF band，and then to report the door or window is either close or open by using a free download APP，and furthermore to generate an alarm to draw user’s attention if an unauthorized intrusion happened for enhancing home security capability.
Differ from traditional design, signal transmission has been changed to wireless RF transmission, no extra cables or wires required, only needs 2 AAA dry batteries (3.0V 600mAh) for providing working power. This sensor is the most power saving，should 20 events triggered a day, the batteries can last more than one year.
When batteries power is reaching low margin, APP will issue an alarm message automatically to inform user to replace batteries.
The sensor can be sealed on indoor side of windows or doors of your house as you wish. Location had better higher enough to prevent kids touching.
Totally 8 sets can be installed under same gateway, and the maximum distance
Should be limited within 80 meters from door or window to gateway( inside IP CAM).
Mutual Specification for RF series sensors
