How will the sensors COMMUNICATE to the monitoring device?

RS-232 cable is generally standard as a common and reliable method for up to about 200 ft.

RS-485 converters can be used to extend the RS-232 range from 200 to over 1000 feet.

Wireless weather stations can be created with 900 MHz transceivers with Outdoor Line of Sight with 2.1 DB antenna at 9 miles (14 km).

Serial to Ethernet Converter transmits the serial data from the sensor transmitter to the monitoring computer using the existing Ethernet Local Area Network. The device driver will create a virtual serial port that can be used by WeatherMaster software. The serial to Ethernet converter is useful for large facilities such as an industrial plant or hospital. Instead of running miles of cable from the weather station on the roof to a computer on the first floor, users can take advantage of existing Ethernet cables to connect.

For TCP/IP communication over a LAN, the Weather MicroServer can make weather data available to any computer or device on the network. Examples include Weather Display consoles (device), computers running WeatherMaster software, or any device with an Internet browser. The MicroServer also can upload weather data automatically to Internet sites such as Weather Underground, CWOP, and the CWS Weather Server.

As you are planning for a weather station installation, consider how/where cables will be routed and/or connected to existing systems. Depending on the configuration and how much cable comes with the sensor, measure whether it will be sufficient or if additional cable will be required.
