compatible transmitter

315MHz and 433MHz wireless connections are very commonly used by consumer electronics including weather stations, home automation remote controls, power consumption meters, car alarms, and also many DIY projects.

compatible transmitter

Post by bernard » Thu Dec 15, 2011 10:47 pm

I'd like to work on an arduino project that will communicate with some byebyestandby switches and relays but which requires me to transmit as well as receive messages.

Can anyone recommend a suitable transmitter for use with the RXB6 module (and a source for it)?

Bernard ;)

Hi Bernard,

I've used them with this one from Jaycar:

There's a neat Arduino library called "VirtualWire" that makes it really easy to use the 433MHz receiver shield and one of those Jaycar transmitters as a simple serial link between two Arduinos. That's exactly what I used for this rocket telemetry project a couple of years ago:

The VirtualWire docs are here:

Just a quick question on this same subject for my home wireless weather station:
Has anyone written code for the La Crosse TX7U or TX7NU transmitter? Thanks in advance.

The code from the Weather Station project in the "Practical Arduino" book appears to almost work. The green (D6) LED flickers different when I power off and on one of my TX7NU temperature/RH transmitters. No temperature is displayed in the Serial Monitor window. Does anyone have the data format for the TX7U/TX7NU? Any suggestions? I am using the ASK Receiver Shield 433 Mhz and an Arduino Uno. I don't have the full La Crosse weather station transmitter since I only need wireless Temperature and RH right now.

Thanks in advance.
