Smartrek sensors communicate over a cooperative mesh network. That is, they all take turns and exchange data to the network coordinator, the Gateway. Once data has been received, the Gateway transmits to a computer (tablet or smartphone) over a Bluetooth link.
You now have all the collected data at your fingertips, providing valuable insight and information. Either on a computer and/or, optionally, on the Cloud.
Also, as a result of the bidirectional communication capability, you can control and activate/deactivate connected sensors and/or objects.
