Hey Everyone!
I just used an RF transmitter and Receiver of 315Mhz to send and receive data through PIC18 Controller! The language I used to program it was mikroC.
First I used a monopole straight antenna with it and used the transmiter to send data to receiver! the transmission and reception was working for quite a good range. Next, I thought of attaching both the reciver and transmitter to my two micocontroller modules. I did this so that when my Master(Transmitter) would transmit some data, then my Slave(receiver) could acknowledge him back too that the data had been received successfully. After I programmed it that way it was still working fine. The problem came when I testes it’s range which had reduced considerably. The range went to almost more than half as it was when I was usuing just a single transmitter and receiver.My question is does anyone know what might be the problem as to why my range of data communciation has reduced so much? And can anyone please also do give me some tips as to how can I resolve this issue?
I have attached a picture of transmitter and receiver I am using! I would be very thankful If I could get some pointers on how to solve this issue!
Hi Shamas,
You’ve mentioned in your post that “First I used a monopole straight antenna with it and used the transmiter to send data to receiver! the transmission and reception was working for quite a good range.”
Could you please tell us how did you test the working?
I interfaced both my controllers with separate lcds and whatever I transmitted from the transmitter, the receiver received it and showed it on it’s lcd! That is how I tested it.
like for example, I sent ‘Master’ from the transmitter and the receiver received it and displayed ‘Master’ on it’s Lcd screen
