1. A wireless sensor with a control algorithm comprising:

  • a transmitter configured to transmit using a carrier frequency and modulation, via an antenna, at least one of a coded burst pattern and an IP (Internet Protocol) address pattern to a surrounding environment of said wireless sensor;

    a receiver configured to receive at said carrier frequency and modulation, via the antenna, a reflected signal of at least one of said coded burst pattern and said IP address pattern from an object in said surrounding environment of said wireless sensor;

    a processor configured to;

    record a time of completion of transmission of at least one of said coded burst pattern and said IP address pattern;

    measure a received signal strength intensity (RSSI) of said reflected signal;

    reject said reflected signal if said RSSI is more than a threshold value then wait a random time before transmitting again;

    keep said reflected signal for further processing if said RSSI is less than said threshold value;

    detect at least one of said coded burst pattern and said IP address pattern from said reflected signal and record a time of completion of detection;

    calculate from said time of completion of transmission and said time of completion of detection a distance, and an approaching speed of said object in said surrounding environment of said wireless sensor;

    evaluate said distance and said approaching speed of said object to determine whether said processor needs to activate a device or a function.
