RF Transmitter Receiver Pair 433 MHz - FS1000A

Model No: WIR-00003

TK. 149.92

Availability: In stock


Category: RF

Supplier: Made in China

This pair consists of an RF transmitter and receiver. These can be interfaced with Encoder and Decoder ICs. For better accuracy, antenna should be used at transmitter and receiver ends.


We have two different 433MHz RF modules: the RXB6 and the FS1000A. Both of them runs with the same code and user interface.




Quality of reception

Very good

Good but not great

Transmitter Signal Noise

Q: How can I use it as a remote controller? I want to control two motors with this. Questioned by anikpro, 17-Apr-2013

You can get some idea from this tutorial.http://www.techshopbd.com/index.php/tutorial-categories/arduino/interfacing-rf-shield.Here we have controlled relays by RF module.You can do the same with motors.Though in this tutorial we've used Piduino,it is compatible with any microcontroller. Answered by A.R, 18-Apr-2013 05:01 AM

Q: Hmm I have do a lot of work to use it. can you bring 2.4 GHz 6 channel radios and receiver? I need one for RC some RC application. Questioned by anikpro, 18-Apr-2013

Hope you have already got our mail about your enquiry. Answered by A.R, 18-Apr-2013 08:58 AM

Yes, but I'm not interested about that Way because bringing a single one is very costly. If you bring some of them, it will be cheaper. So please bring them as a regular product of your site. Answered by anikpro, 18-Apr-2013 10:02 AM

Q: How can I pare this to module? What is the basic communication method? Please explain. Questioned by risajal, 10-Dec-2013

You may need encoder and decoder IC depending on which module you want to interface.Please go through the wiki page of the product for clearer idea. Answered by A.R, 10-Dec-2013 12:35 PM

Q: 1.I need this.how much time will be needed to be available.it is out of stock. 2.I want to use this in a rc system with encoder and decoder ic.but in my project diagram tx has 6 and RX has 8 pin.vcc and ground are double.anyway is it possible to use this as a rc system with HT12E & D. 3.I want to control several loads from far.have you any suggestion plz? Questioned by astable, 24-Dec-2013

1) These are from China so,at least one month will be needed. 2) Yes,these are compatible with HT12E and HT12D. 3) We will suggest you to check the transmission range first because we don't know by 'far' you mean how far. Answered by A.R, 29-Dec-2013 04:31 AM

We had the wiki link here earlier but later we found out that the current lot of this product does not match with the previous ones. The previous ones were 433 MHz and so was stated in the wiki page too. But the current lot we got is 315MHz. This is why why removed the wiki link for this time being. Sorry for this inconvenience.
