Campbell Scienti c o ers sensors that emulate and mea-

sure the moisture content and temperature of similarly-

sized twigs on the forest  oor.  ese 10-hour fuel mois-

ture and fuel temperature sensors are o en incorporated

in our pre-con gured or custom  re-weather stations.

When connected to a datalogger with telemetry capability,

the user can automatically monitor changing fuel condi-

tions without having to visit the measurement site.  e

fuel moisture and fuel temperature sensors are compat-

ible with our CR510, CR800, CR850, CR10X, CR1000,

and CR3000 dataloggers. Compatible telemetry options

include spread spectrum radios, narrow-band radios, cel-

lular phones, and satellite transmitters.

CS205/107 Fuel Temperature

To measure fuel temperature, both the CS205 Fuel

Temperature Stick and a 107 Temperature Probe are

required.  e CS205 provides a ponderosa pine dowel

that is fabricated to USFS speci cations. A hole is

bored into one end of the dowel, where our thermis-

tor-based 107 probe is inserted.  e 107 measures the

temperature inside of the dowel.  e CS205 and the

107 are sold separately.

CS505 Fuel Moisture Sensor

Our fuel moisture sensor, the CS505, reports the status

of small-diameter (10-hour) forest  re fuels as percent

moisture by weight (1%=1 g). It consists of an epoxy-

encapsulated electronics package that uses Time Do-

main Re ectometry (TDR) technology to measure the

moisture content of the 10824 10-hour Fuel Moisture

Stick.  e sensor produces a ±2.5-Vdc square-wave

frequency that is read using an analog or pulse channel

on a Campbell Scienti c datalogger.  e datalogger

then converts the frequency measurement to percent

fuel moisture via a quadratic calibration.

10824 10-Hour Fuel Moisture Stick

 e 10824 10-hour Fuel Moisture Stick consists of a

ponderosa-pine dowel fabricated to USFS speci ca-

tions. It has a ½-inch diameter and a 20-inch length—

the same dimensions as those used on the traditional

weighing fuel moisture racks. Each dowel has under-

gone two additional sorts to optimize probe-to-probe

repeatability and to allow probe interchangeability

without individual calibration.  e response of the

CS505 sensor is similar to the traditional weighing

racks because the entire dowel surface is exposed for

moisture exchange.
