Optical sensor assembly

A sensor system comprising:

• a plurality of optical-based sensors for measuring the presence of an analyte in an analyte containing medium, each of said sensors being disposed a housing having an external sleeve and a mating member housed within said external sleeve, wherein each of said sensors includes a body, internal circuitry, and an internal coil housed within its body, said internal coil being configured to receive electrical power from an external power supply and to transmit data;
• at least one reading device comprising drive circuitry coupled to a primary coil, said primary coil configured to transmit power to and receive data from said internal coil of said plurality of optical-based sensors;
• and
• a processing device configured to interface with said reading device in order to receive said data from at least one of said plurality of optical-based sensors;
• wherein said mating member of said housing is configured to mate with a device in contact with said medium containing said analyte to be measured such that said optical-based sensors are brought into contact with said analyte containing medium.

A method of measuring the presence and concentration of an analyte in a medium comprising:

• providing a sensing apparatus comprising a housing having an external sleeve and a mating member disposed within said external sleeve, said sensing apparatus further comprising an optical-based sensor disposed within the mating member of said housing, said optical-based sensor including a body, internal circuitry, and an internal coil housed within its body, wherein said internal coil is configured to receive electrical power from an external power supply;
• mating said sensing apparatus with a device that configured to be in fluid communication with said medium containing said analyte to be measured,
• exciting said internal coil by electromagnetic induction using a reading device;
• receiving at the reading device data from the optical-based sensor relating to the presence of an analyte in a medium;
• and
• transmitting said data to a processing device.

A sensing apparatus comprising:

• a housing having an cavity disposed in an outside surface of the housing;
• an optical-based sensor capable of measuring the presence of an analyte in an analyte containing medium, said sensor disposed within said cavity in said housing, wherein said sensor includes a body, internal circuitry, and an internal coil housed within its body, said internal coil being configured to receive electrical power from an external power supply;
• and
• drive circuitry configured to communicate power to and receive data from said sensor,
• wherein said housing is configured to connect with a device in contact with said medium containing said analyte to be measured such that said optical-based sensor is capable of contacting said analyte containing medium.
