A system and method for sensing and indicating air pressure within an enclosed space is described. The system comprises a pressure sensing device and pressure indicator further comprising a housing enabled to house a plurality of electronic devices and having an opening, an elastomeric membrane covering the opening of the housing and capable of flexing inwards and outwards, a light emitting device to provide an illumination and a projector for projecting a positive pressure symbol and a negative pressure symbol. The elastomeric membrane flexes inwards along with a representation of the positive pressure symbol with an illumination of a first color when the pressure within the enclosed space is positive and the elastomeric membrane flexes outwards along with a representation of the negative pressure symbol with the illumination of a second color when the pressure within the enclosed space is negative.
