1-wire® Weather Station - Starter Kit
Description
1-Wire® Weather Station Starter Kit contains all needed elements to convert your PC computer in to a profesional Weather Station. It lets you view the weather outside from the comfort of an armchair, measuring wind speed, direction and temperture. Easy to build and install with free windows software. Additional 1-wire units can be added to expand your system.

1-wire
The 1-Wire network protocol was developed by Dallas Semiconductor/Maxim as a way to interface to range of small devices, such as digital switches, sensors and analogue-to-digital converters. Every 1-Wire device contains a unique identifier preset at the factory. As the name suggests, the devices are networked together by a single wire that acts as a physical medium to communicate between a host and a large number of devices attached along the wire. It is also capable of powering these devices through the same wire. In practice, a second wire is actually needed to provide a return to ground and complete the circuit and most 1-wire units actually use a 4-wire RJ11 cable. See here for a description of the 1-wire concept >>
Starter Kit Contents
The basic kit contains all the parts to make a working weather station including; wind vane cup anemometer main housing quality printed circuit board containg temperature and wind 1-wire devices mounting pole all mounting screws, nuts and bolts assemblly instructions Free software The kit does not contain a RS232 or USB 1-wire PC interface which need to be ordered seperatly. The 1-wire PC interface is supplied with 2M of RJ11 cable. You may need longer lengths which can be ordered below.
Included Software
The 1-Wire Weather Station software takes weather station data from a One-Wire Weather Station. The data includes: temperature, humidity,speed and direction of the wind, and the amount of rain fall. The data is continuously updated at a specified interval, reflecting any changes in weather conditions. The data is also stored in a text/log file that users can review.
displays instant and average wind speeds displays wind direction displays outside temperature. Calulates and displays wind chill temperature and dew point displays humidity readings (needs optional humidity unit) displays barometric pressure (needs optional barometric pressure unit) displays rain fall level (needs optional rain fall unit) Logs data in a CSV data file can send data across the internet using http protocol to a specified weather Servlet. can also receive data remotely from itself or other 1-Wire Weather Stations. support up to 20 extra TAI8520 Temperature Sensors. chart display - shows all data on a data/time chart display built-in device configuration Wizzard to simplify device settings 1-wire Weather Software Download >>
PC Interface
You can connect your 1-wire weather station to your PC via either an RS232 adaptor or a USB adaptor. The adaptor has a 1-wire RJ11 connector into which you can plug your 1-wire cable. You can have up to 200 1-wire devices connected to a single adaptor. Serial daisy-chain connection is the most common (most 1-wire units have an "in" connector and an "out" connector to simplify this) but other connection methods can be used. Please see here for more information about 1-wire networks.
RS232 to 1-wire Adaptor The DS9097U-S09 Universal 1-Wire COM Adapter is a sophisticated RS232 to 1-Wire Adapter which performs RS232 level conversion and actively generates the 1-Wire communication signals. The DS9097 can be used with the 1-Wire Weather Instrument and with any of the 1-Wire modules. 1-wire Drivers >>
USB to 1-wire Adaptor The DS9490R is a USB bridge with 1-Wire RJ11 interface to accommodate 1-Wire receptacles and networks. The DS9490 can be used with the 1-Wire Weather Instrument and with any of the 1-Wire modules. 1-wire Drivers >>
