Finally! Pictures! (Big Update)

We started getting our items in and finally got to do some assembly (and disassembly) of our parts. We chose to use the lower half of a remote controlled tank, which 'was' a German Tiger. This will allow us for a large platform to house everything and gives us good maneuverability.

These 2 pictures shows the inside of the tank where we are most likely going to mount the on-board microcontroller (circuit board on right). Nothing is plugged into it and nothing is programmed yet, we just wanted to see how it would mount up:

These 2 pictures are the beginnings of our sensor modules. These will interface the gas sensors to our microcontroller. We use these to determine the levels that have been detected as well as determine how much gas we want it to detect to trigger the alarm:

Here is a shot of our sensors and Zigbee boards:

First batch of items

Just ordered out first batch of items for our project. Only cost us about $200 and will be (hopefully) only half of it. Hopefully meaning nothing breaks or needs replacement, but I wouldn't mind purchasing more parts for add-ons and enhancements.

Carbon Monoxide Sensor - MQ-7 x2
Methane CNG Gas Sensor - MQ-4 x2
LPG Gas Sensor - MQ-6 x2
Humidity and Temperature Sensor - DHT22 x1
XBee Pro 900 XSC RPSMA x2
900MHz Duck Antenna RP-SMA x2

We still need our chassis which will consist of the lower half/hull of a tank with the top taken off replaced by plexi glass. We also need our microcontroller, camera, alarms, leds, and little odds-n-ends.

Next blog updates will be of our first constructions and first lines of coding.
