Product Type: MX-05V
Working voltage: DC5V Quiescent current: 4MA
Receiving frequency: 433.92MHZ
Receiving sensitivity: -105DB
Size: 30 * 14 * 7mm External antenna: 32CM single core, wound into a spiral
Transmitter technical parameters：
Product Type: MX-FS-03V
Launch distance: 20-200 meters (voltage is different, the effect is different) Operating voltage: 3.5-12V Dimensions: 19 * 19mm
Work: AM Transmission rate: 4KB / S Transmit power: 10mW
Launch frequency: 433M
External antenna: 25cm ordinary multi-core or single-core
Pin arrangement from left to right: (DATA; VCC; GND)
Remarks：
VCC voltage and module voltage should be consistent, and to make the power filter;
Antenna greatly affect the receiving effect of the module, the best access 1/4 wavelength antenna, generally using 50-ohm single-core wire, the length of the antenna 433M is about 17cm;
The position of the antenna also affects the receiving effect of the module. When installing, the antenna should be as straight as possible, far away from the shielding body, high voltage and interference source. When using, the receiving frequency, decoding method and oscillation resistance should match with the transmitting.

This was the third RF RX/TX that I tried. I'm using the Radiohead RH_ASK library which claims compatibility with most of the "inexpensive" 433 Mhz devices available ... there are several different manufacturers and types. This one actually worked as described in all the YouTube videos with the latest RH_ASK library with Arduino UNO (R3) and Pro Mini. Of all the YouTube videos out there on this subject, I noticed the best and most informative ones use this type - FS1000A Tx & 080408 Rx. I'm not saying the others (e.g. SYN115/480) - I just didn't have much luck with them.

Did it work? Yes. Did it work as good as I wanted it to? Absolutely not. I could only get about 3 inch range even with using antennas on transmitter and receiver. Even then it was very intermittent when the signal would reliably be sent/received. If you think these will just work at a long range - move along. Without an antenna they would not work at all. Some reviews and online videos claim you can get a few centimeters without an antenna, but I could not get them working at all with no antenna. I read some reviews that say they are missing a 2nd coil. And mine too did not have this 2nd coil. But other online sites say it is not needed and another part takes its place. I don't know enough about them to know if that is true, but if there was a revision you would think they take the time to fix the silk screen lettering issues !!! These modules are different when visually comparing to online videos that show how they work. The 2nd coil is not there on the transmitter. And on the receiver a lot of the videos show a large resistor on the board, and mine did not have the resistor. Also one commenter pointed out it is missing a capacitor...mine also did not have the capacitor. I soldered one in, but did not do my test with antenna but without the capacitor soldered in so I can not confirm if that is required or not.

Love these little guys work great for anything at few meters lengthy you can stretch that length out to 10’s of meters with the right antenna and power supply. Add filters (ferrite bead and capacitor). Also you can pull down the data pin with about a 10k resistor. They work awesome. Love them for simple projects .((((EDIT:)))) Some people don’t understand that these need antennas and that they need to be tuned. They have to be dialed in with the pot in the little green box. I get them all to work at 25/100ft. (Maybe farther for some but I run out of yard.).

The receivers have an AGC so unless the transmitter constantly changes, they'll just output noise. The AGC imposes a minimum data rate of 100 bits/sec. Only in a few random cases will the receiver appear to show some correlation with a DC signal. Hi on the transmitter shows as high on the receiver. Low on the transmitter shows as low on the receiver. There's no analog output. They instantly turn on so they're better for remote controls than an SPI radio which needs a bunch of commands. There's no way to change the transmitter frequency. They don't come with antennas. You have to solder on antennas.Sadly, couldn't get any useful range using any voltage or antenna combination. They might be able to transmit a single code for an on/off signal or massively error corrected data at a very low rate below 1kbit/sec but the AM system just wasn't robust enough to send a unique code at 2kbit/sec.

Like other reviewers, I found that the receivers worked well enough for capturing my RF power sockets' codes. However, the transmitters worked VERY POORLY. Some could not produce a signal strong enough to be detected by a receiver mounted on the same breadboard.Following advice in another review, I searched Amazon for FS1000A transmitters whose product images showed two copper coils. Those other transmitters have been working very well: they generate strong signals that the power sockets can detect no matter where I place them in the house.

Todos los receptores buenos (5/5), un sólo emisor malo (1/5). Los probé con la librerÃa TinyRF, especÃficamente, "TinyRF_TX.h" y "TinyRF_RX.h", para los sketchs de transmisión y recepción respecivamente. Usé una placa arduino uno para el receptor, puesto que la placa de desarrollo mh-et live attiny88 carece de comunicación serial para el serial monitor del ide arduino.

I know this device got a lot of negative reviews, but I think the reason is most folks buying these don’t know what it’s used for or how to use them. I’m an amateur radio operator, and was able to attach a 17.3cm wire bunsoldiering itnto the tiny hole labeled ANT for antenna. I could pick up data transmissions from these modules well over 200 ft. I’m using these as a model rocket homing beacon. Using my RF analyzer, software defined radio, and frequency counter, I found that my units were actually transmitting on 434.050 MHz or 434.0100. So your units may have worked, but we’re not on the frequency you expected (433.92Mhz). If you don’t have a frequency counter, you can use a radio scanner to tune up and down the 433 MHz band to detect a transmission from your module. Also, the DATA pin is spelled backwards (ATAD) on the main board. Aside from that, I was able to get mine to transmit my call sign every few seconds with an Arduino Nano in Morse code and/or data, using it as a model rocket locator beacon. These also transmit in the AM mode. I was very happy with my purchase!

I purchased this set to send sensor data from around my house to a central data collection location. After spending considerable time trying to get it to work, I found there are components missing from the transmitter PCB, preventing it from working. How can these be sold in this condition?

These RF Tx/Rx are complete junk. Even with the proper length of wire for the attenae it was way less than the advertise distance/performance. Max distance was about 5' from each other. Not sure how the other review stated they got over 200' of distance where the majority of reviews got way less.The chips were soldered so poorly that the resin and solder splashe were everywhere and pins were sticking out by 3-4mm on the backside.Seller was quick to response, but did nto provide any other usefull info other than diagrams of the pin-outs.

I gave a star for each unit that worked (3/6)!

Receiver range is less than 1 meter at -10C.Cheap but you get what you pay for. No instructions whatsoever and conflicting information on the internet. Seller was on no help.
