Re: DS18B20 Max Distance

Hi all, I have been following this thread for quite some time. I have been working on building a solar hot water heater controller. I thought I found a solution until this evening. I ended up buying a 1-wire Add On board for a PiZero to use for the Solar Hot Water Controller. I had it all up and run...

Also one other requirement for the temp sensor is that it needs to be water proof.

Cheers

Re: I2C to 1-Wire RPi Zero - Solar Hot Water Heater Build

I was hoping to use that board with this 12V DC pump . I will certainly take a look at the post you mention. I do have experience with main power. I have done quite a bit of mains electrical work in the past. I have minimal pi experience. I did build a hestipi, which uses mains power. My level of se...

I broke down and ordered a 1 Wire PiZero addon from PiHut. It'll hopefully be here by next week. I'm hoping it'll do what I need it to. Fingers crossed! Until then, I beleve I'll be following some advice given on other post here stating : JohnsUPS wrote: ↑ Sun Jan 13, 2019 12:51 pm You want to wire ...

I2C to 1-Wire RPi Zero - Solar Hot Water Heater Build

Hi all, I am new to the forum. I am looking for assistance in a Solar Hot Water Heater Controller build. My goal for this project is to use 3 temperature sensors (hot water holding tank, solar panel, and outside temperature) and 1 KY-019 relay board. Power will come in from line and be converted via...
