Hey Everyone!
I just used an RF transmitter and Receiver of 315Mhz to send and receive data through PIC18F4520 microController!
First I used a quarter-wave monopole straight antenna with it and it was working fine! Then something went wrong! Now the receiver just receives data for once and then doesn’t altogether!
Also, when it was working, it just worked in line of sight scenario!
Could some one help me with it please and also I would be very thankful if someone could explain to me the specs I require if I need to mount a helical antenna on it rather than a quarter-wave monopole one?
Or how can I increase it’s distance of communication?
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,
The receiver receiving only once issue might be the presence of a bug in your code. Please add the code in your nect post.
The RF module can have a maximum distance of 30 meter only, you can’t get more than that. The datasheet of that particular module will help you to identify the maximum possible range with and without antenna.
Ofcourse they work efficiently in line of sight only as in the case of any other RF communication devices.
If you are looking for long range communication and better performance the RF modules are not a good option!
