The FS1000A 433MHz is a wireless RF module, cheap in price, and easy to use. The modules are for wireless systems and projects. In this module, the transmitter can only transmit data and the receiver can only receive that information. It means you can only send information from point one to two and not from two to one.
The receiver module is a little complex, consists of an RF tuned circuit and some operational amplifiers to amplify the received carrier wave coming from the transmitter. It then provided the coming amplified signal to a phase lock loop (PLL) which permits the decoder to lock onto a stream of digital bits which allows better-decoded output.
We can develop the project RF-based home automation system using this module to replace the use of conventional switches in the home and other places. The project involves a transmitter that sends signals to the receiver while the receivers are wired with loads.
The FS1000A 433MHz wireless module is one of the cheap and easy to use modules for all wireless projects. These modules can be used only in pairs and only simplex communication is possible. Meaning the transmitter can only transmit information and the receiver can only receive it, so you can only send data from point A to B and not from B to A.
The module itself cannot work on its own as it required some kind of encoding before being transmitter and decoding after being received; so it has to be used with an encoder or decoder IC or with any microcontroller on both ends. The simplest way to use it is with the HT12E Encoder and HT12D Decoder IC.
Today we are going discuss about FS1000A 433MHZ RF transmitter & XY-MK-5V RF receiver module pair for wireless communication between two arduino boards or two raspberry pi boards. These modules are also available to work on other frequencies that is 315MHz and 330MHz but there is not any difference in their pinout and working, the 315MHz and 330MHz modules will also use same code that is used for 433MHz modules in arduino and raspberry pi. Below we will discuss about the pinout details, performance, how to use and where to use this module.
FS1000A (433 MHz/315 MHz/330 MHz RF Transmitter) & XY-MK-5V (433MHz/315MHz/330MHz RF Receiver) is a pair of low cost radio frequency module for one way wireless communication for arduino, raspberry pi and other platforms. This module is used by vast majority of electronics DIYers due to its low cost and easy implementation. The transmitter part can be operated from 3V to 12V and the maximum output can be achieved on 12V with 17cm antenna at both sides. However the receiver required stable 5V. These modules are available in three different frequencies which are 433MHz, 315MHz & 330MHz therefore you can buy according to your frequency requirements. The max stable data transfer rate is 10kb per second.
The module only transmits one way because in this pair one is a RF transmitter and other is RF receiver. But it can be used for verity of purposes where there is not any requirement of two way communication for example wireless temperature sensor, switching home or office appliances, and transmitting data. However if you want two way communication then you can also use other modules like HC12, NRF24L01 etc.
FS1000A 433MHZ RF transmitter & XY-MK-5V receiver module can be used in any project where there is a requirement to send data through air under short distances. For example if you require a continuous temperature monitoring inside or your house or outside, temperature monitoring of machines running in factories. Moreover it can also be used to control electronic appliances in home or in office, making home or office security projects, door locks etc.
Using FS1000A 433MHZ RF transmitter & XY-MK-5V receiver module is very easy, for using this module you have to have two platforms attached on each side for example if you are using arduino for building your project then you must have two arduino boards in which one should be connected with the transmitter and the other with the receiver. The connection of the transmitter and receiver is not very difficult you only have to connect three wires of the transmitter with one arduino board and three wires of the receiver with other arduino board. There are also two different parts of codes available for the project one for transmitter that can be saved in the arduino attached with the transmitter and other part of code should be saved in the arduino board connected with the receiver. The above simple explanation of how to use the RF module will work on any project you are building using these modules but the code and wiring may be different in different projects and you will get that information in the details of the project you are building you will find many projects using this module with guide and codes online.
I have recently completed a project using an Arduino nano and a Fs1000a 433mhz transmitter module to control a WattsClever remote power socket. The unit works well but reliable range is limited to around the 20m mark which is a little short of where i need to get.I have experimented with aerials 165mm to 175mm long.The Fs1000a is currently running on 5v but can accept voltages up to 12v. I would like to increase the voltage to the Fs1000a to try and boost it's range but am not sure if this increase would cause trouble where my arduino data pin connects to the transmitter. I have not been able to find a data sheet on the Fs1000a so thought someone else may have come accross this and be able to help.
I am using these 433MHz modules. According to the product information, I can supply the transmitter from 3-12 Volts. I am sending the data from an arduino (5V data) and want to power the transmitter with 12V that I am still be able to receive the data some meters away from the transmitter.
The receiver will only work on 5V - think about it - why would a higher voltage help it receive more! On the other hand the transmitter WILL give more power at 12v and I had no problems continuing to supply it data from a 5v Arduino-type-chip. The range almost doubled. I'm using a 17cm wire on the transmitter and nothing on the receiver. Here's a blog I wrote on the subject. Forget the 40m indoors - that only works if your walls are made of paper. With a cottage and stone walls I reckon half of that.
First thing to note is the incorrect silkscreen printing on at least the modules I have. They have data in and Vcc mixed. It works as printed, but then the Vcc goes to the modulator transistor base via 10k resistor (27k on some modules) and just saturates it and lets the oscillator/TX transistor run all the time when it gets some supply. However, the data line from your microcontroller goes to where the Vcc should have gone and modulates the oscillator by switching the power on/off. That "kinda" works. The "power" your transmitter will get will be no more what your controller data pin can supply. Of course, at least Arduino type controllers can supply some current from data pin (LEDs light up) but one can't expect it to be a proper supply for the transmitter.
Also the 'Ant' label is slightly wrong on my modules. It goes straight to the collector of the oscillator/transmit transistor and skips the output capacitor. That doesn't affect the transmitter very much otherwise, but one should keep in mind that the module voltage has a straight DC path to the antenna if the antenna touches ground.
I can confirm JRE's note about the Vcc and Data inputs to the ASK transmitter being incorrectly labeled. I had been struggling with a Tx/Rx pair for days, trying to figure out why, even with 17.3 cm dipoles, I couldn't get better than about 5 feet transmission range. For my application, I just need good reliable message transmission with a room, so say about 20 feet. Swapping those connections and I was suddenly out the door, down the hall, and through walls, and still getting 100% solid reception. This mislabeling is insidious, because the transmitter "works", just poorly.
Since people keep bringing this up, the 5v logic "high" that comes out of the Arduino pin has nothing to do with what voltage you need to feed into the transmitter's data pin to make it output a pulse. The Vcc to the transmitter goes to a transistor's collector. The Arduino's output goes to the base. All the Arduino's pin needs to do is be high enough to switch on the transistor. It doesn't need to be 1/2 Vcc. I have now successfully tested one of these FS1000A's with an 18v supply, still driving the 5v data pin of an Arduino. It works perfectly, and the range goes up even more than at 9v or 12v. The data sheets on the transistors used on this board show all lowest max collector voltages to be 20v. Perhaps it's "gutsy" pushing them to 18, but it worked great.
Hey I got a FS1000A wireless transmitter from ebay, the description says that it can go in sleep mode,
to save power consumption, if the data pin is grounded, on the radio transmitter module, but how do I do that ?
If I pull the plug between the arduino and the radio transmitters data pin, the radio transmitters goes in deep sleep mode,
but if I connect the FS1000A datapin to the arduino, the FS1000A draws power, even if I execute the command
I used a DS18B20 to sense the temperature with Arduino
I use a 433mhz transmitter to send the temperature on my raspberry
the raspberry I have the receiver, and then I store the temperature in a database
if Arduino and raspberry are close (20 cm), no problem, I get the temperature
if I remove the raspberry Arduino, I get nothing
the transmitter and receiver antenna
can you help me ?
best regards
Hi. great tutorial. I have two questions:
1. Would this work if I used one arduino connected to the receiver and this usb to serial connector attached to the transmitter (arduino.cc/en/Main/USBSerial)
2. Is there someway that I could make it work by connecting the receiver/transmitter modules to the RX/TX pins (pins0&1) on the arduino?
