The IR detector is biased to the ground using a resistor, and the detector\'s signal is fed back to the analog input pin on the micro-controller. The image shows the schematic and PCB layout of the node. The PCB layout is as small as possible because of the PCB cost of my local manufacturer (Eurocircuits)
Combined evaporation-Induced and surface tension induced flow, the void size of the wet film during the coating process is given by the following equation: hole size. Viscosity-The relevant number of the Ag northwest suspension, B is the surface tension gradient caused by the temperature gradient. Wetting film thickness from 1. 63 to 4. As shown in the figure, when the coating speed is increased from 2 to 10 μm, it is 78 μm.
The missing upper roof will be glued to the parallel plane area of the lower roof later, but don\'t do it now, because we still need to make some circuit connections on the roof first. Having learned how to fold a house, you can now use a pencil cutter to create folding lines along dotted lines by carefully cutting a thin layer of thick paper.
