Pneumatic Energy Harvesting and Monitoring

An apparatus comprising:

• a number of sensors configured to detect a number of parameters in a fluid system;
• an energy harvesting unit configured to generate electrical energy from a fluid in the fluid system;
• and
• a controller in communication with the number of sensors and the energy harvesting unit, wherein the controller is configured to process measurements for the number of parameters detected by the number of sensors and control operation of the energy harvesting unit and wherein the number of sensors and the controller are powered by the electrical energy generated by the energy harvesting unit.

A method for monitoring a pneumatic system, the method comprising:

• monitoring for a number of parameters using a monitoring device connected to the pneumatic system, wherein the monitoring device comprises a number of sensors configured to detect the number of parameters;
• an energy harvesting unit configured to generate electrical energy from a gas in the pneumatic system;
• and a controller in communication with the number of sensors and the energy harvesting unit, wherein the controller is configured to process measurements for the number of parameters detected by the number of sensors and control operation of the energy harvesting unit;
• and
• powering the monitoring device using the electrical energy generated by the energy harvesting unit.
