Fuel Moisture Sensor
QFM101 Fuel Moisture Sensor measures the moisture content of the
material on the forest floor or other natural area to help forest
managers assess the fire danger. It uses a carefully selected and
prepared pine dowel to exchange moisture with the environment. The
sensor measures the moisture content of the dowel by its electrical
capacitance.

Figure 37 QFM101 Fuel Moisture Sensor
A thermistor, located in the dowel where it fastens to the base,
measures the temperature of the dowel giving the estimated
temperature on the forest floor. This measurement is available as a
second input to the controlling data acquisition system.
