Arduino Code for RFBee control RelayShield
Hi, i have the shield mounted on an Arduino,A push button is attached to the Arduino controling a relaywith a time delay.
I was wondering if i could also have anotherArduino with an Xbee module to have a wirelessPushbutton aswell
Yes,you can use a RF bee of RF module to control wireless.For more details, you can check the design files on the wiki page.
Are the relays able to be controlled using the digital I/O pins of an Xbee module or does this require an arduino? Would like to use the Xbee API control to change the state of the pins on the Xbee thus controlling the relays
Yes, you are right. The relay can work stand alone controlled by XBee without Arduino.The control pins are connected to the I/O pins of XBee socket. For more details, you can check the design files on the wiki page.
Does the board make any use of this bank of pins? I need to connect a switch to the arduino and the simples way would probably be to remove the pass-through header that connects these to the relay board and solder directly to the arduino. The docs make
Hi Yuri,are any of the other pins not in use? If so, can you please identify them?
Can I use the RN-XV XBee compatible WiFi module from Roving Networks instead of the XBee 315/433MHx RF module? It needs 3.3V power.
You can plug in the jack, but RFbee has Atmega 168. But RN-NV hasn't.So if you use jumper wire to connect MUC to control could be work.
Do you have a dimensioned drawing or possibly 3D CAD files for this device?
Sorry, we haven't.Just only in Eagle file.
If this can 3A @ 120V AC, so can it do 1.5A @ 240V AC?
In theory it is, but we didn't test that.
The description above quotes "70W DC or 35V AC" but the relays depicted in the product images show relays that support 3A @ 120VAC or 24VDC - is there anything about the board that reduces this capability or is the description wrong? I'm looking to con
The reason why we change the parameter to 70W DC or 35V AC is to pass the check of being able to the US market.Anyway, it should be ok to control 1A at 120VAC.
Nice board. I know the products cannot suit everyone but here is what I experienced.1. I did not need the radio function2. I would have liked to have some IO pins broken out - I added a 2nd shield between Arduino and this one.
Actually all seeeduino are basically same, just not in same RAM or speed.So you should depend your need and product feature to buy.
I purchased 5 copies of this board and just took delivery. The boxes are dated June 2012. I also downloaded and viewed the Eagle files but they do not match the product. Two of the relays are turned the opposite direction. I wanted to try making a daug
Hi Mark , thanks for your feedback , we have uploaded the eagle file on the wiki page , please check it :p
using the relay shield remotely with a XBEE v2, using XCTU i'm able to send API commands to the remote xbee to turn its pins on, I hear the relay click but none of the LEDs I have attached in NO config work, even stranger no voltage is seen when using
Hi,the operation voltage is 9V(more or less),so you nedd supply the 9VDC power to the Relay Shield.,or it can't be worked.
I am a software guy so pardon this question. It appears that there is no connection to the XBee serial terminals. Can I connect the arduino RX/TX to the XBee socket so that the arduino can talk to the XBee?
Yes , you can .Or you can use it with a Xbee Shield .http://www.seeedstudio.com/dep...
Hello, that's a nice apllication to industrial use but, it's possible to have more than 4 relays in a shield or mountind more than one shield? Thanks.
Sorry, it only have 4 relays and cannot mounted more than one shield.
I am planning to use this with Arduino Uno. If I power and communicate to the uno thru USB, will I still need to provide the 9v to this shield? Thanks
Hi there .Yes , it still need to be provided external power(7-12v) .
Is see that the supply voltage has a 12V MAX rating. Would it still be ok to use a 12V supply?a
Yes,it is ,but suggest it had better not to do that.
The sample code for this Relay Shield (v1.3) specifies using pins 4, 5, 6 and 7 for the 4 relays. However, my shield is not responding. I'd like to know whether this pinout changes for the Seeeduino Mega 2560 ADK board. I'm assuming like everything els
No, just plugged into the Seeeduino for now. I'm not powering anything off the relays currently. I just have a meter hooked up checking for continuity across the normally open to common so I can tell if the relay actuates. Do I have to have an external
Can these relays be run at 12VDC with 3.4 Amps on a continuous basis?
Hello, it cannot , the maximum switch is only 2A, for 3.4A, it will harm the relay.
What happens, if the contacts will be at 220 ??????VAC?
Hello, the rely will be damaged when it connect with 220VAC. To be safe, do not do this. If you want to use 220VAC , you could use other relay such as Grove - Relay(ht
Im in the field of remote automation. I already have 30 of these units in service and they work fantastic. However the Xbee headers would be a lot more useful if they were rotated by -90deg to allow room for the rp-sma connectors on some xbee boards. I
Hello Drew, thanks for your feedback and advice, it is really helpful for us. I will take this idea to consideration for the next version revision of this product.
I'd like to be able to monitor the thermostat in our house as it turns on and off using 24 VAC. Can I do this with the shield or is it output only?
Yeh, the max switching power is 70W DC or 35V AC, hence, you can use it to turn of and off 24VAC device. "Can I do this with the shield or is it output only?"--Sorry, i could not understand clearly.
Sorry if the question wasn't clear. I don't want to "turn on and off a 24 VAC device". I want to detect when a 24 VAC device is turned off or on externally. I want to read the state of a 24 VAC line (on, 24 V or off, 0 V). I want to monitor when a ther
Okay, i get it. This shield is a relay control board, it can't be used to monitor your thermostat is turning on and off. While, you can have a look at our AC current measure sensor(Answer by: admin on 2018-12-18 02:39:29

Hello, sorry for the inconvenience caused. We have re-upload the demo code, please try to download it again :D
Hi there, in the wiki, it does not mention that these relays can handle AC! I want to control 24VAC water valves for my project, is this possible?
Looking at the photos, the relays themselves indicate 3A 125VAC.
interface XBEE aboard this shield is compatible with WIFI BEE module?
Yes, it is :D
Can this safely switch 2.5 amps @ 120 volts AC?
On the relay itself it says 3 amps 120V AC, so i figured it was good, but then in description i see only 70 watts DC and 35V AC? seems kind of odd, you mention watts DC and then only mention a volta
Thanks, and i also kind of got my answer after reading back to page 8 of the questions lol... where Steve Chang mentions that it has to be advertised rated at 70 watts and only 35V in the US for legal reasons or something... understandable :P
Is it posible to custom order quantities of 5 to 10 units without the XBee headers and without the power connector? I'm providing a product based on this relay board and for it to fit in the project case with the other componets, the first thing I do i

Would like to have a circuit diagram.
Hi Takashi.You can download it from this website(www.seeedstudio.com/wiki/image....
I power my Arduino UNO with a 14V battery using DC jack.Arduino automatically steps down the battery voltage to its needs.Is it ok to power this shield through Arduino in this situation or shall I have to put an external 9V battery?
I need to use a 14V battery for some other components in my application (which is off-grid so I don't have a USB plug there).I need to know if it's ok to power the shield through arduino with a 14V battery.
I looked through the wiki and all of the forum questions, but don't see anywhere that mentions whether the 9 VDC jack is center positive or center negative. Also, what are the dimensions for the plug?
It is center positive, DC9V 500mA power, It looks like a standard Size K 5x2.1mm coaxial plug. Hope that helps
I'd like to use my arduino to open/close the garage door. Is the a correct relay to use?
Hi Jason.Yes you can.But please attention: The max switching power is 70W DC or 35V AC.
I went to the Wiki website and downloaded 2 code examples, however, my Winzip says these files are not WinZip formated and can't upzip them....please advise!!
Hello, please try to use other IE explore such as Chrome.
I have recently bought a relay shield board and bluetooth bee for a project I'm working on. I'm wondering is it possible to write the code for the board as it is or do i need an arduino board to do that if so which board would I need? I want to be able
Hi,Ryan,Yes,you need an arduino board to control these modules.you can refer our wiki to code what you want.you also can ask for help in our froum,as a maker，i
My Ehternet Arduino uses Pin4 for the SD card. Can I re-route the relay to use another pin besides 4 for its D3 s oi can use the SD?
Yes you can, Tim. To solve this problem you might need a single grove relay module http://www.seeedstudio.com/dep... . I hope this could be helpful.
Where can i find the schematic for Relay Shield V1.0? And Could you tell me if all the pins are usedfor just the shild no addons (as is shild
Hi.The schematic of v1.3 is almost the same to v1.0. And NC1--digital 7,NC2--digital 6,NC3--digital 5,NC4--digital 4.
Which pins does this shield specifically NOT use and what is the easiest way to access them (specifically the analog pins)?
Hi.If you just use the relay shield without using RFBee,there are 4 digital pins would be occupied(digital 4 to digital 7).And you can use Base Shield as a transfer board.
Where can I download a PDF file of the board schematic?
Hi,we will add a one,thanks for your attention.
Does SeeedStudio Relay Shield v1.0 socket for RFBee work with Bluetooth Bee?The one with built in Atmega168, as well as the one without Atmega168 chip?Does it work with other compatible Bluetooth Bee with Xbee form factor i.e. from DFRobot? Tha
Hi,you can use bluetooth bee with relay shield,maybe you need modify the program.The one has a Atmega168 chip can be used alone:upload a firmware,etc.Maybe other bluetooths could be compatible with ours,it depends on the specification,
