This invention describes a micro sensor device which may be used in a variety of sensor applications to monitor, sense, or measure a concentration of a material within a sample. The device comprises an integrated sensor head and a body portion coupled to the integrated sensor head.

The sensor head has a tip portion adapted to be inserted into a sample, a light source for emitting a beam of light into and through the tip portion with the tip portion capable of interacting with a substance within a sample to produce a reflected pattern of light, and a detector for receiving the reflected pattern of light. The body portion comprises a processor operatively connected to the light source and the detector, the processor for controlling the light source for emitting the beam of light, for receiving the pattern of reflected light from the detector, and for processing the reflected pattern of light to determine the concentration of a substance within a sample.

The invention is simple to use, provides extremely quick results and high resolution, is easily transportable and uses relatively inexpensive components which makes it a commercially viable product.
