Re: Joining multiple DS18B20 sensors

Thanks!! Now your design is perfectly clear. I'm going to order a 3.3v to 5v level shifter and a ds2482-100 and give it a try. I've been saving reel end scraps of cat5 just for something like this.
Thanks again!

Here's the waterproof sensors I use: https://www.adafruit.com/product/381 Have you ever considered using Node Red software to display temps in charts and also control your relays? You can also send email alerts if temps get too high or low. Node Red runs great on a Raspberry and I think is included ...

Re: Joining multiple DS18B20 sensors

Thanks! A picture is worth a 1000 words as they say.
In your application, is the ds2482 close to the RPi or is it a distance down the line?
A schematic would be great too. I appreciate your information and sure there are other readers that do too.

Re: Joining multiple DS18B20 sensors

Great information! Several months ago I spent a far amount of time googling how to extend the distance of ds18b20s. But never found anyone with your success. I understand the cat5 pairs wiring configuration but am not clear on the physical layout of the ds18b20s in relationship to the ds2482? You me...

Re: Joining multiple DS18B20 sensors

Is the DS2482 used to obtain the 369' or is it just the DS18B20 sensors driving this distance? You want to wire all of the sensors in parallel. This will avoid the star topology, and you can go quite a distance. I currently have an installation of five DS18B20 sensors along 369 feet of CAT6, and the...

Best and cheapest are very hard to use in the same sentence. I would look for wireless since a wired station can be like a lightning rod with a cable directly into your house.

Re: Garage door video streaming

I'm doing something similar with webiopi and a Axis IP network camera.
It involves adding a few lines of code to the index.html file that is used to display the webiopi buttons on your web page.
I would be glad to share the code with you to get you started in a direct email.

When viewing the same network camera IP stream in Chrome, the picture is very clear and sharp. On the RPi using the HDMI output, the picture is not near as clear and sharp. Maybe not a fair comparison?
