If the sensor is connected to the data logger, check the output of the sensor
in data display in

is making reasonable measurements.
5. Overview
The HFP01 Soil Heat Flux Plate uses a thermopile to measure temperature
gradients across its plate. Operating in a completely passive way, it generates a
small output voltage that is proportional to this differential temperature.
Assuming that the heat flux is steady, that the thermal conductivity of the body
is constant, and that the sensor has negligible influence on the thermal flow
pattern, the signal of the HFP01 is directly proportional to the local heat flux.
