GreenBeard Posted May 16, 2017 Share Posted May 16, 2017 Hi Guys, does anyone knownof someone that can set up a Rasberry PI to monitor, switch diffetent items on and off report on min and max temps ect. I want to start a project to build a unit to control the detials in side both my tents... using nirmal household heated fan, small extraction fan and must maker. anyone with ideas, input will be awesome...

Trickerst Posted August 3, 2017 Share Posted August 3, 2017 Hey dude, I have a few up and running doing this already. Which monitors do you want to use? I'd recommend using the DHT22s for humidity, just replace them yearly. And then a DS18b20 for temp (much more accurate than the temp sensor in the DHT22), which is waterproof so you can even stick it in a DWC bucket. I'd run HAssbian and add a relay to control all the other systems. EDIT: Just realized that I necro'd this... Quote Link to comment Share on other sites More sharing options...
CG420za Posted August 4, 2017 Share Posted August 4, 2017 This is french to me, but i'm keen to learn. I want to to do the same thing. Automated lights, fans, temp and humidity meters. What would be the 1st thing to buy/learn? Quote Link to comment Share on other sites More sharing options...
Totemic Posted August 4, 2017 Share Posted August 4, 2017 Subbed for this one too. Been wanting to do this for some time. Quote Link to comment Share on other sites More sharing options...
Trickerst Posted August 5, 2017 Share Posted August 5, 2017 @CerealKilla and @Totemic You'd need to learn how to use linux as a start. Then learn how to use terminal in linux You can start out by buying 1x "raspberry pi zero w" 1x headerpin set 1x case for RPiZw 1x 32GB microSD card to store the operating system 1x power supply RPi 2x DS18B20s (waterproof temperature probes) 2-4x DHT22 (humidity and temp sensors) 1x 4ch or 8channel relay depending on how many items you want to turn on or off You could use the temp probes to get accurate temp readings in the tent or in the DWC (if you have). You can use the DHT22s to measure relative humidity inside your cab/tent at different locations and externally. Then you would need an operating system to run the wireless webserver, Home Assistant is the easiest to setup and it has a built in webserver and can control the relays via GPIO. All in all I can help you guys are in CPT Quote Link to comment Share on other sites More sharing options...
CG420za Posted August 7, 2017 Share Posted August 7, 2017 Out of curiosity, what would this setup cost? Quote Link to comment Share on other sites More sharing options...
Justin Hemp Posted August 7, 2017 Share Posted August 7, 2017 I'm in Cape Town 2, I will check out the price first. Do you have pics of the setup T? Sent from my GT-I9505 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Trickerst Posted August 7, 2017 Share Posted August 7, 2017 Out of curiosity, what would this setup cost? About R 1000 all included The sensors are fairly cheap, the pi is about R280. Only issue is you need to either get a hammer installed header pin set or fire up a soldering iron for the pi zero You could rather get a RPi3 but they cost R700.

JBKush Posted September 6, 2017 Share Posted September 6, 2017 Very interested. Been designing a theoretical setup for a large greenhouse based off of a Pi or Arduino. Not as many as I expected doing it. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
