Transmitting IMU data wirelessly

Wireless & IoT
1

Hi

I have a IMU 6 DOD V4 board and I would like to transmit its data wirelessly. I dont want to use Bluetooth as distance is a consideration. I am thining of using the TTL serial output from the IMU and linking this to a Data Radio Module Transciever ( HAC-UM96 ).

The only problem that I can see at this stage is the incompatible baud rates;

The IMU ouputs at 115200 baud while the Transciever operates at 9600 bps.

Any ideas or thoughts? I’m new to the subject so any help is appreciated.

Thanks

If you are in the US or Canada, have you considered the XBee Pro 900 MHz transceiver? Probably a bit more robust and it can talk at 115 kbs.

Im in New Zealand, but I think it will still work here, only thing is it says it uses a “156 Kbps RF data rate” whereas the IMU only outputs at 115Kbps… do they have to match?

Thanks Ralph

range objective? This drives the solution approach.

IMU - what’s the average SUSTAINED rate. 115Kbits/sec sustained is not achiveable with low cost products. But that’s a heck of a lot of data. I’d think that the actual informatiion rate for the IMU would actually be in the order of a few hundred bits/sec.

range ideally would be 75m +

But even if the IMU is not 115Kbits/sec sustained, doesnt the Transciever still need to support 115Kbits/sec? otherwise at times information will be lost…

Thanks
