A miner’s canary(‘s) cage

The gas sensors and stepper door control are now together, sensing high levels of Carbon Monoxide or Methane will open the bird cage door (See previous post). I put in a small push button to act as a test switch- like on smoke detectors. I don’t think it is quite ready for a bird just yet. Need to take it off the breadboard and put it onto something more permanent and clean up the wires. Thought it would also be good to put clear acrylic behind the electronic components- so the canary can’t attack the exposed parts.
