3. Getting Started: Creating a Wireless Sensor
Network
The steps to quickly creating a wireless sensor network are:
1. Obtain the required hardware and software
2. Create a model of the network using default names
3. Configure all the devices in the network
4. Send configuration string file to the datalogger (optional)
5. Program the datalogger to communicate with the CWB100
6. Connect the CWB100 to the datalogger
7. Apply power to the wireless sensors and initiate auto-discovery
8. Verify that data is being transmitted
3.1 Hardware and Software Required for a WSN
3.1.1 A205 CWS to PC Interface
The A205 CWS to PC Interface is used to communicate between wireless
sensors and a computer via a USB cable. One end of the A205 has a type B
female USB port while the other end has a four-pin female connector that
connects to the four-pin male connector located behind the battery pack of a
CWS sensor.
The A205 is necessary for configuring wireless sensors prior to deployment
and is also useful for testing and troubleshooting them. When connected to a
USB port on the computer, the A205 provides power to the wireless sensor.
When connecting the A205 CWS to PC Interface to a
wireless sensor, be sure the sensor has been powered
down (battery pack disconnected) for at least 15 seconds.
