Abstract
Disclosed is a sensor for detecting the proximity of smart devices previously connected to the sensor using the IEEE 802.11 protocols. Importantly, the sensor does not operate using a Bluetooth® connection, which would require the smart devices previously connected to the sensor using the IEEE 802.11 protocols to also have Bluetooth® protocols enabled. Enabling such Bluetooth® protocols uses more battery than having the IEEE 802.11 protocol adapter enabled. The sensor references a list of previously connected smart devices and attempts to connect with any in range, if none can be connected to, the sensor emits an audible alarm signal. Further, no application is required for the sensor to operate.
