The sensor is used in a low frequency oscillator circuit, which changes frequency as the relative humidity changes. The output of the oscillator is fed into the microprocessor. Unlike others, our humidity sensor will not be damaged by prolonged high humidity. The sensor is used in a low frequency oscillator circuit, which changes frequency as the relative humidity changes. The output of the oscillator is fed into the microprocessor.
Some systems economize by using a less capable sensor indoors.
It has a vertical baffle across the middle. On each side is a collector, shaped like a miniature coal shovel, with high sides and an open end. The baffle funnels rain water into whichever collector is up. The collected water spills out and new rain is immediately funneled into the opposite collector, which is now up. Installation is easy in the perfect location with our unique wireless rain gauge.
