Published Date: 05/06/2013

Description

Of all common environmental parameters humidity is perhaps the least understood and most difficult tomeasure. The most common electronic humidity detection methods albeit highly accurate are not obviousand tend to be expensive and complex (See Box). Accurate humidity measurement is vital to a number ofdiverse areas including food processing paper and lumber production pollution monitor
