Overview
The WSA is a weatherproof humidity and temperature sensor for outdoor use. A radiation shield protects the sensors from rain, hail and radiated heat, and its curved plates let air flow across the sensors so that heat from roofs and nearby surfaces does not distort the reading. Typical uses are meteorology, greenhouses and industrial sites. Humidity can also be output as absolute humidity, enthalpy or dew point. It mounts on a wall or a pole.
