I am trying to use one of these 433MHz RF receiver modules to intercept transmissions from a weather stations outdoor sensor.
While I have the reciever in line of sight of the transmitter (only about 15m away) I can receive the signals quite ok, but as soon as I move the receiver to another room no more than 3-4m further away I am having all sorts of reception problems.
My first question is what sort of antenna works best with these modules? I am currently using a 31cm piece of wire (which seems to give the best results), but I have also tried a 433Mhz stub antenna from another reciever I have and it didn't seem to work well at all. I probably should mention that the module at present is plugged into a breadboard, which could be part of the issue.
I also came across this forum post that suggested that the modules are prone to ESD damage, is this true? The module I am using also uses the same IC as is mentioned in the post.
I would much appreciate anyones thoughts and/or experience with these type of modules.
