A Temperature Tracker Source:     Github

Each Raspberry Pi is an edge processor that is connected to a controller Microbit. The controller microbit is then used to interface to the other trackers wirelessly via radio. The microbits are connected via mesh system, each microbit amplifying the other's signall till it is able to reach the controller microbit.

When temp is too high, an alert is sent out and the red LED represents that.

Demo 1: The entry of a microbit that is not recognised by the Rpi controller causes an alarm to be sent and the blue LED to light up
