“In this project we have used two types of different R.F Module like 433Mhz and 315Mhz Interface into Pic16f877a,HT640 for R.F Encoder,HT648 for R.F Decoder Ic’s.Hence in this we have to use two sensors one is for temperature sensor LM35, another one is potentiometer, the two sensors have an output of analog signal so that analog signal is fed into to two adc channel of pic16f877a and the corresponding digital output is get from the serial port, continuously watching the real time parameter monitoring purposes.”
