This is a Major project on Cordless Thermometer With Digital Display using RF transmission

It is a Technique for transmitting measured temperature to a distant located
point(15 meter). In this project a temperature sensor LM35, a voltage to frequency
converter ic LM331 is used in transmitting end, this frequency is transmitted. In receiver
end by using ic 4518 dual BCD up counter ic, IC 4511 BCD to 7 segment latch decoder
ic,ic 4533 3 digit BCD up counter ic, IC LM78L06 voltage regulator ic; temperature
measured and showed by 7 segment display in digits.
