In its introduction, a brief description of the panel. Its main part is a kit AVT 2389 – Four thermometer sensing LM 35, their accuracy in my case is ok 1C (or rather Difference between the sensors – in pairs at intervals of time and come from different series). Complement the thermometer is “fanbus” (regulator) based on a well-known to all LM317T, enables a regulation in the range of 6V ok to 10.5 V
