WSDL WxShield for Arduino
What's a Weather Shield?
The WxShield is a replacement for the OS console unit (WMR88, WMR100, WMR200, WMR918, WMR968, etc).
A little block diagram will help to explain how this all works.
The Big Picture
The setup contains the following components:
- A Windows computer -- it can be just about any size of computer, from netbook to desktop.
- This computer is running data-logging software, which collectes weather data reported
by the Arduino CPU module. Typically, this is the Weather Station Data Logger (WSDL)
software application (freeware, available here).
- An Arduino computer (CPU) module, connected to the Windows computer with a USB cable.
You can learn more about the Arduino module here.
- The WSDL WxShield plugs into the Arduino module and contains:
- A radio receiver that can hear transmissions from Oregon Scientific wireless sensors.
- A connector to which an external antenna must be attached.
- A sensitive barometer (the Bosch BMP085).
- A standard telephone jack for connecting a remote temperature/humidity sensor.
- An external antenna to receive wireless sensor transmissions. This can be mounted directly
at the WxShield, or it can be mounted some distance away with an extension cable.
- A Sensirion SHT15 temperature/humidity sensor is mounted on a separate module, and connects
to the WxShield with a standard 4-conductor phone cord (RJ14).
