Humidity Sensor Module (See note.) ES2-M
Model
Note: This is a replacement item. One Module is provided with the
ES2-HB/-THB. Always attach the Humidity Sensor Module
when using the ES2-HB/-THB. Approximately 7 VDC will be
output for the humidity output if the Module is not attached or is
incompletely attached.
