Fuel Moisture Sensor

This sensor monitors forest fire fuel conditions by measuring the moisture content of a connected fuel stick. It uses advanced measurement technology to determine moisture levels and is commonly used in fire-weather monitoring stations. Those stations feed the wildfire weather monitoring for utilities and the PSPS weather station networks WWG deploys along high fire-risk corridors.
