3、ing a part work principle is a single slice machine to make use of the DS18 B20 rightness temperatures to carry on collect, then carry on a wireless to send out, carry on a decoding after receiving to carry to receive signal, after carry out a temperature manifestation.Temperature control part work
4、principle from keyboard importation desire enactment of temperature.The temperature control signal sends into CPU a processing, output control signal through a PID calculate way, Be received and dispatch electric circuit blast-off to go out by wireless and accept to carry to receive signal to control the semi-conductor Wen Kong4s device to attain the temperature of desire enactment through the CPU processing.This text carried on frame diagram a design to the hardware and the software, the pro
