Thermal dispersion airflow measurement

A system comprising:

• a transmitter device;
• at least one probe assembly comprising a communications component and a probe bar comprising a first cross-sectional shape, wherein the communications component is communicably coupled with the transmitter device;
• wherein the at least one probe assembly comprises:
• a first sensor node device at a first position on the probe bar, the first sensor node device comprising at least one sensor and a computational circuit, wherein the computational circuit communicates sensor data to the communications component,
• wherein the first sensor node device comprises a second cross-sectional shape that is complementary relative to the first cross-sectional shape of the probe bar,
• the at least one sensor is surface mounted onto the first sensor node device to measure properties of airflow across the probe bar, and
• the at least one sensor is thermally isolated from the computational circuit.
