 || There are three wires that need to be soldered onto the Airwick PCB. These connect power/ground and the PIR signal to the HAHnode board. In addition, there is a link wire that needs to be fitted to the Airwick PCB. Ideally, use difference colours of wire to avoid confusion.  The 'link' wire.  This wire bridges the Gnd signal between a couple of points on the PCB. || {{6929392059_61f1d49e22_b.jpg?320}} ||
 || We cut away the plastic part that used to hold the canister. This allows better access to the HAHnode PCB.\\ Initially I left too much tube, the arrow shows where to cut, I used a hacksaw, just above the tongues. || {{6783272238_1202d4a576_b.jpg?320}} ||

 || Wire up the DS18B20 Temp sensor. The insulation tube that is supplied is heatshrink. A quick blast from your heatshrink gun (or a paint stripper gun) will do the job.  || {{6783273502_f2bfcdaa68_b.jpg?320}}\\ {{6929391679_a1571009a9_b.jpg?320}} ||
