Is there any relation, between supply voltage and emitter module output power? I drive that module by 5V (from Arduino), but I have some difficulties with transmission for relatively short distances (cca 100m). Would it be better when the module was drQuestion by: admin on 2018-12-18 02:42:34
"100m" I meant 100 meters. It is not so short distance, and I'm pretty sure the shorter antena can't solve that problem.
The question is can the supply voltage affect transmission range?Answer by: admin on 2018-12-18 02:42:34
In order to make the tx and rx work, do I need
to set all 8 bits to high/low?
Can I leave them all as float in single pair of tx/rx environment?Question by: admin on 2018-12-18 02:42:34
You just need to set one pin of TX module HIGH , then the corresponding pin of RX will be HIGH.Answer by: admin on 2018-12-18 02:42:34
Would I be able to set-up a system with 8 sets of Transmitters/Receivers with 8 Arduino Uno's. Basically I would want to have one master that calls out to each salve (1-7) one at a time, and each slave sends sensor data back to the master one at a timeQuestion by: admin on 2018-12-18 02:42:34
This RF does not support the two-way transmission,and it just send high and low level signals.Maybe this product can meet your needs.

Hi, thanks for your link.
Just receive it. Please someone tell me how to trigger transmitter to send pins to receiver. I supply both with 5VDC.
Hi,there is WIKI can refer to. And also you can go to forum to post you question then more people would help you.
I have been trying for days to get these working but have found nothing. All the examples refer to pt2262 chips which have only one data pin? Does anyone have any working code for Arduino, or can point me in the right direction?
Hi there, thanks for your feedback. You can see there is some customer can success that module.So we would consider to make a example project and attach on WIKI.Thanks.
2KM is for open area, if you want to get longer distance, try to install it higher.
just received my unit.
what is the maximum supply voltge.
both the Rx and TX have supply rating of 5-_9 volts,according to the "manual"
but the website says 5volts
can I run them from 9 volts ?
5V-9V is operating voltage. 9V is maximum.
In the question below, I want to use multiple units for controlling robots simultaneously. Will there be much interference?
Now we put the example on the page, you can see the transmission is slow. Would be has some interference.
Hi there , it is can be used to connect to Arduino .We just distribute this product , so you need to cut the connector and then connect to Arduino PIN port.
I bought this module and i want to use withing a closed big room. Tx and Rx are around 2-3 Meter seperate but its not working. Is this module only work for larger distance. I am using 5 volts supply for both Tx and Rx is this ok?? Because I checke onl
Yes ,it can compatible with arduino that need to be cut the connector .
Hello, I have problems with this module. First of all, when I try to use the receiver with 9V it fail and you can`t use it anymore(2 units failed in the same way). And when I was using 9 V for the transmitter and 5V for the receiver the range was 60 me
sorry Del, we have no the 005 item now.
I see this "Note: Do not warp the antenna or the module will be burned!" thing in the description. Does that mean you cannot bend the antenna? I see pictures of this item where the antenna is straight and I see pictures where the antenna is wound-up in
I'm sorry for this issue. Wrap the antenna couldn't burn the module, but the effect will be affected. In order to get a good effect, do not wrap or stretch the antenna.
Would you be willing to post the parts used for these circuits on the Wiki page?
After connecting these for the first time, the transmitter module failed. The burnt part is a SOT223 (I think), connected to the big solder blob on the transmitter mod
The transistor which you are looking at SOT223, the number describes the actual physical shape of the transistor, and not the type. Are there any other numbers on the device? All is not lost, this transistor is the PA or power amplifier fo
No,it isn't. So long as transmitter in a distance more that 1m, it can work.
If 4 push button switches are connected to the transmitter, will the receiver outputs be the same as the transmitter inputs for all 16 combinations of switch states?
Yes, but when you are transmitting 0 (all inputs low), nothing is transmitted. But on the output is also 0.
The transmitter/receiver pair worked beautifully. The documentation was pretty bad, but by reviewing the comments on this website it was fairly easy to understand how the units operate. Note that you are not required to adjust any of the encoding pin
Hello, we do not sell sct-013-005 at present, while, you could send your requirement to our Wish page(http://www.seeedstudio.com/wis..., we will consider it according to the demand.
Hi,there is a tutorial for this product,you could refer to it(http://openenergymonitor.org/e.... If you want to connect it to Grove expansion board, you should cut the cable and ma
Hello i would like to use it with a servo trigger from sparkfun. I am a very very novice on it ...and i am french . Can i plug in the rx out on servo trigger switch ? If there is somebody could help me it will be verry cool thanks a lot
Sorry , we do not sell it at present. May it will be one of our products in future while you can put your idea to our Wish page , thanks``
I would like to know if another pair of same RF link kit disturb the operations each other in same range area ??
yes, when measure the current, notice you should just see only one"leg" of the target system . if with currents opposite phase , this sensor would see no current .
I got all sorts of problems with my set.
1) The unit only sends when at least 1 data bit is high. If all are low, VT on receiver is low)
2) The data bits are shuffled (sender d0,d1,d2,d3 'connects' to receiver d2,d3,d1,d0, in that order)
If the datasheet is correct, the PT2272 is prettty hopeless for my purpose. I think I'm going to remove the PT2262 and PT2272 and interface the RF-side directly from my microcontrollers...
Hi Dear Customer, we suggest use them separately. please refer our wiki (see here: http://wiki.seeed.cc/2KM_Long_Range_RF_link_kits_w_encoder_and_decoder/) about how to use the 2km kit. thanks. Bill
Hello, I am afraid no. More details please refer to http://www.datasheetcatalog.org/datasheet/PrincetonTechnologyCorporation/mXusxsq.pdf Thanks.
Hi Dear Customer, Sorry for the previous reply and just confirm with design and the point to multipoint mode works well. thanks. Bill.
@123Fake - I want to thank you for that honest feedback. It is utterly frustrating to buy "28-mile" RF radios only to find out it takes being in outer space to even get 3-miles. The only REAL specs have to be found by user reviews such as yours. Thanks again.
