Reading Device in Wired Communication With a Probe Having an Embedded Memory Device

A monitoring system comprising:

• a reading device;
• and
• a probe having a housing, the probe is electrically connected to the reading device via a wired interface;
• the probe comprising:
• a physiological sensor configured as a Wheatstone resistive bridge balancing circuit;
• a memory device integrated within the housing of the probe such that the sensor and memory device are prohibited from being separated from one another during use by a user;
• the memory device is arranged in parallel with the sensor;
• wherein communication between the reading device and the probe occurs via the wired interface utilizing a same number of electrical connections between the reading device and the Wheatstone resistive bridge balancing circuit as would be required if the memory device was eliminated.
