I am using a circuitry to send data through wireless.. using RF of frequency 433Mhz
my circuit is as follows
the problem here is that this works but the range is only 2m
i had also attach a wire antenna of about 5cm to both the transmitting and receiving module.. but it does not work
iam somewhat confused here.. here in my circuit diagram it uses 750k ohm between the pin n0. 3 and 4 of encoder for oscillator and 27 k ohm at the decoder end..
but in some tutorials i have seen 1M ohm at the encoder and 33K ohm at the decoder..
well i have seen what iam doing in many tutorial too..
can some one explain this? does iam doing somthing wrong?
i have seen in some tutorial the resistance is of 1M ohm at encoder side and a 33k ohm at the decoder side..
i hav also seen 750k ohm at the encoder side and a 27k ohm at the decoder side in some other tutorials...
but i did experimented both and both works..
but the problem is with range
