Title: Whole home project.
Post by: kb1ojr on December 11, 2015, 01:40:42 AM

Ok so here is what I would like to accomplish, with as little cost as possible but also keeping somewhat simplicity in mind. I am not a programmer of this nature however I am a linux nut.

I have the following equipment.
Raspberry pi2 (I have a few of these)
Arduino UNO

What I would like to build. In order of priority

- A full featured weather station that reports to Wunderground,
This includes Temperature, humidity, precipitation and wind speed / direction.
(what would be the equipment I would need to do this, what do you use?)

- Also has internal temperature monitoring of 3 or more zones in the house.

- Pool Temperature monitoring

- (this might be a bit much but also PH, Chlorine, and whatever else a pool needs to have monitored)

- Pool motion detection (at the water level of the pool I am trying to figure out how I can add a motion sensor, so if something goes in that is not supposed to be in the pool I get a audible warning somewhere)

-Sensors for all the home windows and doors.

- possibly camera hook ups as well.


This is probably asking a lot being I know very little of how all this works, but this is what I think this thing can do.

I am going to start with temperature monitoring and see how it goes I figure that is the cheapest easiest start to get a feel for this. So far I have a TMP36 sensor for my Arduino, but I am unable to make it work. I also do not think this is going to be my going forward sensor. I am thinking of getting a few DH11 sensors. Any recommendation on starting out with monitoring temp with the gear I currently have or what else should I get to help. Any advice is appreciated. Thank you.

I'm using a combination of DH11 and DH22 conented via Arduino/MQTT and for outside and my pool I use the waterproof sealed version of the  1wire DS18B20 temperature sensor directly connected to GPIO 4 on my RPi's

Using Arduino Nano or Mini with MQTT allows you to create relative cheap wireless sensors/input/output devices (temp/humidity/light/motion/switch/relay etc. - search for MySensors on the web)

Thanks for the info, so for this you just have a PI with an arduino running with a few sensors attached? Seems simple enough. I will have to research the MQTT not sure what that is. Think I might grab those 2 sensors they are a good start I think.

Also I see the Eden board v2 is a good addon, but I cannot seem to find it anywhere?
