Systems and methods for sensing pressure

A system, comprising:

• a pressurized container configured to hold a pressurized gas and to supply controlled amounts of the pressurized gas to the system as required;
• a sensor comprising a wireless transmitter, the sensor configured to sense a pressure in the pressurized container and to periodically transmit, using the wireless transmitter, information related to the pressure in the pressurized container;
• and
• a control unit comprising:
• a wireless receiver configured to receive the information transmitted from the sensor;
• a network interface communicatively coupled to a communication network;
• and
• a transmitter configured to transmit the information received from the sensor through the network interface;
• and
• a data processing center communicatively coupled to the communication network, the data processing center configured to receive the information transmitted by the control unit and to predict based on the information received from the control unit when the pressure in the pressurized container will reach a predetermined threshold.
