Davis 6544 the Module of a meteorological station (Davis Instruments) for programming of inclusion of heaters, fans, etc. devices
The specialized WeatherLink 6544 (Alarm Output) interface with alarm functions has the connecting block and allows to use the weather station for control of fans, heaters, etc., relying on the set weather parameters.
By means of this interface it is possible to adjust individual "recipes" of alarm which will control four switches. For example, you can establish an alarm clock which will switch only when the speed of wind exceeds more than 20 miles an hour, at the direction of wind between southern and western, and it between 6 o'clock in the morning and the 9th evenings. "Recipes" can be both simple, and difficult, depending on your purposes.
The software and the registrar of data includes WeatherLink.
