Marty Grogan told us of his sensor's capability to detect changes
in humidity of the atmosphere surrounding it - sounds like a new
humidity sensor is due for release shortly? ;>

The use of the sensor to detect condensed water may be more of an
immediate reality:
Could the system as outlined be used to replace a cooled mirror
dew-point detector? (And so get rid of the problems associated
with dirty mirrors).

Dew point sensors are the best in very humid environments where
other types fail, but the problems of the mirror becoming
contaminated after frequent condensation and re-evaporation are
difficult to address.  Any comment?
