DIY Any Arduino? Lets see em!

[cybergasm]

my grow is up stairs and i want to have a dht11 sensor wireless to give me data to my desktop downstairs or my phone. any ideas?

I just finished setting up a multisensor with 3x dht11, 1x relay for maximum 230v 10A + an extra 5v power source for future sensors.
As you can see there are 3 cables sticking out at the bottom for the dht11s to measure temperature and rh in 3 heights (if there is major temperature difference from top to bottom you can get a indication that somethings wrong).
I also added a 230v relay with a cable going through the box with sockets on each end.
And finaly 5v power for the arduino that I split up so I have a extra 5v power source ready to go.

I use Arduino with MySensors and domoticz.
My setup is like this:

Server/controller:
Raspberry pi 2 with Domoticz (home automation software). With domoticz you get a dashboard where you can control a huge number of smart devices (zwave, Philips hue, robot vacuums etc) and custom arduino sensors.
You can create a mysensors gateway with a arduino and a Nrf24 wireless module, you hook this up to the raspberry and domoticz will detect it and you can now control mysensors nodes from domoticz.

Nodes/sensors:
Mysensors has a huge library with pre-built code and examples for many common arduino sensors.

All you need is an arduino and the Nrf24 wireless module + one or more sensors and actuators of your choice.



In domoticz (acsessable through web and app) you can get graphs from your sensors and create rules, for example you can add remote controlled power sockets and turn the fan on if the temperature reach X degrees.
Hook up a 12v waterpump and a moisture sensor and you get automatic watering.

Dope af.. I got a Uno and a Node32mcu. I want to hook up a rechargable power source to a shield and load code for wifi readings of temp humidity and possibly rez temp. I use a W1209 to run a micro and I got a AC voltage temp controller for the water dispenser I use as a chiller.

I have boxes of old Arduino crap that will probably never see the light of day lol... that stuff is so interesting though!

To go wireless.
Look at esp8266 ore esp32
And how to integrate with Google sheet
It's really simple to setup.
You need a multiplexer for more than 1 analog io..
