USB wireless link between weather station and PC

Wireless & IoT
1

I have a wireless Oregon Scientific weather station that receives data from the sensors wirelessly. The base station then transmits the data to the computer via a USB cable. The computer uploads the data every minute to a weather webpage I created. As it is now, I must keep my weather station base unit attached to the computer by a USB cable. I’d like to be able to get rid of that wire. Basically, I need this:

Weather Station Base unit - USB port ==>> RF tx/rx ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~RF tx/rx =====> Computer USB port

I assume it is a bi-directional signalling setup. I am not asking for a design, just ideas. I understand electronics, just have never delved into the wireless world. Thanks much!

I have a CostCo LaCrosse weather station. Wind speed, indoor/outdoor temp, rain gauge, etc. Like $75.

ALl wireless. Wireless from sensors to display console. Wireless from display console to PC using a USB receiver plugged into PC.

Works well.

Yes, I have seen that one. Unfortunately, I don’t have it. Thanks for the reply.

The Oregon Scientific wireless protocols have all been decoded, so why bother with the existing base station? You can make your own base station, connected to the PC, using an Arduino and a cheap 433 MHz receiver. That way you can get data from a number of modules and do anything you want with it. Here is just one example, but pretty comprehensive: http://wmrx00.sourceforge.net/

Thanks for the info. I think I will try that. I realized about 3 a.m. this morning that LaCrosse is probably doing the same thing. Basically, making the PC another weather station base unit. I really appreciate the help.

Here is another Oregon Scientific decoder/weather station project link http://www.lostbyte.com/arduino-osv3/

The LaCrosse sensors use a completely different RF protocol, but they are easy to decode. I was able to get the temperature out of one without much work, but dropped the project.

The LaCrosse PC software also writes latest data received to a simple text file that you can read/parse.
