Abstract: An apparatus and method for entity data aggregation and analysis is disclosed. The apparatus includes at least a processor and a memory communicatively connected to the at least a processor, wherein the memory contains instructions configuring the at least a processor to receive entity data from a data collection module, wherein the data collection module includes at least a sensor, determine an obstacle datum as a function of the entity data, classify the entity data into one or more obstacle groups as a function of the obstacle datum of the entity data, determine at least an obstacle resolution object as a function of an obstacle resolution template and generate the obstacle resolution data structure as a function of a template form field of an entity specific data structure template, the at least an obstacle resolution object and the one or more obstacle groups.

Abstract: A fluid sensor for sensing a concentration or composition of a fluid, the sensor comprising a first temperature sensing element located on or within a first dielectric membrane and a second temperature sensing element located on or within a second dielectric membrane. An output circuit is configured to measure a differential signal between the first temperature sensing element and the second temperature sensing element. The fluid sensor comprises a first region configured to be exposed to the fluid, and a second region configured to be isolated from the fluid, where the first dielectric membrane is located in the first region, such that in use, the first dielectric membrane is exposed to the fluid, and wherein the second dielectric membrane is located in the second region such that in use, the second dielectric membrane is isolated from the fluid.
