APPARATUS, SYSTEM, SENSOR AND METHOD FOR DETERMINING DISSOLVED OXYGEN CONTENT IN A MEDIUM

An apparatus, a system, sensor, and a method for determining dissolved oxygen content in air and aqueous medium are disclosed herein. The dissolved oxygen content may be determined by irradiating the sensor comprising at least a photo-oxidizable compound by a light irradiation source, wherein the irradiation enables the photo-oxidizable compound to change its luminescent properties based upon photo-oxidation thereby enabling the quantification of the dissolved oxygen content in the medium. The dissolved oxygen content may be captured via the impedance response generated by interdigitated conducting electrode patterns included in the sensor. The dissolved oxygen content registered by the interdigitated conducting electrode patterns may be transmitted to a user device via a short range or long-range communication via an electronic circuit embedded within the sensor.
