Best rf receiver module in terms of range for cheap remote controls

Hi everyone,

For my project i will be using arduino nano.

What i need to achieve is to have more than two hundred transmitters and in the future add even more transmitters if it's necessary. These devices will send data to the receiver just in exceptional occasions. So, the dataflow won't be constant.

That's why i need to buy a very good rf receiver(only one) with a long range which can support these cheap remote controls rf 433 mhz:

Remote Control #1

Remote Control #2

Then, my question is: What rf reciever should i buy?

I've been using rc-switch library for a while, but i will change it if you think i should do it in order to accomplish my goal.

thank you all!

edit: For me Long range is about 100 meters

I bet my view of 'long range' is different to yours ?

(hint)

100m is good enough

Buy a superheterodyne receiver and use a decent dipole antenna.

This receiver (module on the left), advertised as superheterodyne, is NOT:

What is your plan for when all the transmitters decide to send at the same time? What is your plan if all the transmitters decide to send sequentially, so the data transmission is continuous. Do you care which transmitter is sending?

That's very unlikely to happen. Since the rate expected for each transmitter to send data is once a year

But you did not tell us that.

Can you describe the project in more detail, it will avoid a lot of missunderstandings............

a couple of questions about this.

  1. can this module reach 100m?. That will also depend on the transmitter strength, i guess.
  2. does this module work with rc-switch library?

I don't get why this is confusing for you since i said:
"These devices will send data to the receiver just in exceptional occasions."

Explain the whole project is quite hard since this is part of a bigger solution. I just wanted to know the best rf receiver modules that works with the cheap remote controls posted earlier, which can reach 100 meters

kenlot:

  1. can this module reach 100m?. That will also depend on the transmitter strength, i guess.

Possibly, but the environment, where the devices are going to be used, has a much more significant impact than the transmit power, but you have not told where the devices are going to be used.

But we dont know what you mean by 'exceptional'

Rather than use meaningless words, is it so hard to tell us how often the devices will actually transmit ?

  1. can this module reach 100m?. That will also depend on the transmitter strength, i guess.
  2. does this module work with rc-switch library?
  1. Easily, with clear line of sight and a good antenna
  2. Yes

Thank you all for your answers!!.
You have helped me a lot.

Last question, since this is the same model i can assume it is the same device, with the same features, right?

Looks like the same kind of device. Relatively inexpensive. So shouldn't be a problem to buy a few for general testing of your system. You can develop various tests.... eg. all of the transmitters transmitting at once.... etc.

That's to test the system to see if it can handle all possible conditions without operational issues.

For what it's worth, in this thread a poster suggests that the RXB12 receivers outperform the RXB6 receivers and there is little difference in cost.

Many sellers sell on Amazon for $6 on eBay for a dollar
s for testing since you only expect it to work once a year you may have to wait a very long time to get results

But, keep in mind that i am expecting to have more than 200 hundred transmitters. So, i will have the same number of transmissions and transmitters. For instance, for 200 hundred transmitters, which
will send data once a year, the receiver will receive data 200 hundred times a year.
