I am an avid outdoor enthusiast, I like to take my Tacoma on outdoor/overland adventures. Part of this is managing the air pressure of the tires on the truck. While offroad I need to drop the pressure of the tires down to as low as 5lb per tire or all the way back up to street pressure of 40lb. The pressure of these tires would need to be adjusted depending on the terrain. I'm looking for help to build a controller module that would allow the automatic inflation or deflation of the tires to whatever pressure I define. I am looking for help to take off the shelf parts to create a controller module. This module would need to interface with 1) pressure transducer to read the current air pressure 2) Air pressure solenoid: this would be used as an output to interrupt the air flow when the desired air pressure is achieved 3) Secondary solenoid: to be used to allow air to escape when deflating the tires. There would also need to be an LCD control panel that would allow you to 1) Monitor current pressure 2) define intended air pressure via buttons (up or down) or via rotary knob 3) view defined pressure set with #2 4) Select between an inflation and deflation modes. The control of the air compressor should be considered independent of this project and should be assumed that the compressor will automatically turn on/off when the pressure is achieved.
