BBC microbit all inventor and phone PIN

Basically We are creating a model safety slurry pit. We have 3 trigger switches that are triggered when weight is put on the mesh see photo. We basically want a text to be sent when weight is applied to the mesh and we want an electrical current to be send out through the wires and into the crocodile clips which are connected to the BBC microbit. Then we want a text message to be sent from our microbit to our mobile phone. Please see all photos below
