Task: Wireless Sensor Networks
This week's activity is revolving around Wireless Sensor Networks. We were given 2 XBee unit that are meant for wireless communication. We then insert the XBee to find the PAN ID and the Serial High and Low.
END Node:
PAN ID-3332 SH-13A200 SL-40E8CFDC
PC Node:
PAN ID-3332 SH-13A200 SL-40E8CF9E
The serials are required so that another XBee unit can send information by modifying their Destination High and Low Address. Afterwards we can establish a connection from our PC node to send packets of data to the END node to activate programs inside it. In this instance, the letter a will light the LED while the letter b will turn it off. We also worked with group 5 to make a switch/buzzer circuit where we (group 8) became the buzzer circuit and coding for the buzzer while group 5 makes the switch circuit and coding for the buzzer. We were able to activate the buzzer from the switch from a distance without any wires after modifying our High and Low Destination address.
Group 5's END Node:-
PAN ID-3332 SH-13A200 SL-40D5B5F8
For the last activity, we had to make a Star Connection with Mrs Rubaina's XBee unit being the coordinator. We had quite a number of difficulties trying to resolve the coding and circuits, taking at least 6 times to redo the coding and asking around for help. At last we managed to get it working and are able to display the values we got from our sensor. We have not decided in our project whether we want to use a XBee unit as we do need to use a wireless communication system but for now as we have just gained knowledge on it we might implement it.
