Previous post: SP Update 1.5
The stackable headers have arrived from E-Gizmo and finally we were able to test Zigbee wireless communication!!!
First we followed this tutorial from Sparfkun in assembling the shield. Then we uploaded our sketch to Arduino to send ADC readings of the sensor to the gateway and computer. We also programmed the XBees to communicate in Star Topology network.
Below is the package of our "mote". We have here the sensor, sensor signal amplification ciruit, the stacked Arduino, and XBee shield with the XBee. The tube from the sensor goes to a drum filled with water. To test the circuit, we tried to remove then place water to the drum, observe and take note of the readings. We observed that for every 5cm increase, the ADC readings increase 1 bit. For full testing, we are going to deploy this project on a real river.
We have below the gateway which receives the data from the mote.
I made a Visual Basic application which sends a string through the serial port.The XBee plugged into the computer will send broadcasts to the two motes and when the motes receive this string, sensor reading will be initiated. Mote 1 will send immediately but mote 2 will have a delay of 1 second before doing the read and sending the data.
Our next task is improve the GUI of the application, and make it a real monitoring system application with graphs .and database to display and store the data,

Congratulations! It looks really good. Can't wait to see when it gets deployed on the river :)
