When baudrate be set at 4800, the data sent from the
ZigBee transceiver can be received by the computer, but the
data received does not match the data sent. While the data sent
from the wifi transceiver can not be accepted by the ZigBee
transceiver. During the experiments, when baudrate set at
9600 we can see that the data sent in accordance with the data
received, from both of ZigBee transceiver and wifi
transceiver. While baudrate at 19200 bps, data transmission
has an error.
One of the applications of ZigBee and WiFi interface can
be saw on figure 12. Wireless sensor network using zigbee
protocol consist many nodes, they collect the datas from the
environtment, the data collect at the head node. Then, it
convert from zigbee protocol to wifi protocol in ZigBee and
WiFi interface. Finally, the data are sent from the monitoring
area to monitoring center using wifi point to point
communication.
CONCLUSION
From the testing that has been done, it can be concluded as
follows. Network which has been designed is work well where
data sent use the ZigBee standard is acceptable to the Wi-Fi
network, and vice versa. Humidity sensors have 3.8% error.
Distance communication in the process of sending data from
the computer to the access point is 68m. The system can
communicate with both the current value of the baud rate is
9600.
