WRL-10532 Module with Arduino for Wireless Control

Hi everyone,

I’m working on a project with my Arduino and I added a wireless receiver module called WRL-10532 to pick up remote signals. This module works at 434 MHz and can receive simple binary data at ~4800 bps. 

Here’s what I did:

Powered the receiver with 5 V and connected its data output to the Arduino digital pin. Set up a matching transmitter (also 434 MHz) to send simple On/Off commands. Wrote a small Arduino sketch to read the data and toggle an LED or relay accordingly. Tested it across a short room distance (~5–10 m) and it responded fine most of the time.

Now,

The module picks up a lot of noise, so I’m working on filtering out false triggers. I need to try with a longer antenna to see how far it will really reach reliably. Also checking how I can integrate this into my existing Arduino code so it doesn’t interfere with other sensors.

My questions:

How you filtered or cleaned up the data so it didn’t trigger by mistake? Any tips for reliable range beyond a few metres?

Thanks and looking forward to your thoughts!
