We now have the M52-ST social distancing beacon in stock.
The beacon led flashes when two people wearing this beacon come close to one another. Each beacon stores up to 34,304 close contacts that can be extracted using the supplied iOS and Android app.
The app also allows setting of the time two people have to be together, the alarm type (led and/or sound) and a whitelist of up to 45 devices. The transmit power and signal strength trigger value can also be changed to fine tune the trigger distance for different physical situations.
