I am updating a attic exhaust fan that has been in this house for over 25 years and does not currently work, this is exactly what I needed. You have done a great step by step instructional tutorial Thank You!!!!
im trying to purchase a house soon and ill be able to finally build a lot of hydroponic stuff and automate a lot of things with arduino and RPI so stayed tuned,
Yes! i found what may work for my project. I'm building a heating system useing an radiator from a truck. Paint it black, put in a box with glass top mount it on the roof. The sun will heat the fluid (Radiator Fluid or Oil). After reaching around 200*, a valve would open & a 12v pump would push the hot fluid into a hot water holding tank. Then useing a radiator with a fan on the back side. Mounted inside the room you want to heat. the heated fluid pulled from the hot holding tank the, fan would blow the heat into the room. Then the cooled fluid go into a cold holding tank to go back to the roof to be heated again. A closed system with everything running on a 12v or 24v solar system. Controlling the system will be a learning cruve for me. Temp sensor, Open/Close valves, Fans & blowers.. This will help me get started. Thanks
Nice project but a tip of advice. Never, Ever solder mains cables no matter what, the reason for this is as simple as that the solder tension will adjust to the pressure of the connector and in the end will end up in a fire, there's a reason why this is illegal in some country when installing mains inte building.
Soldering tip time....soldering iron goes on one side of the component and board, the other side of the component goes the solder that is touching the component and board. Solder should simultaneously melt on the component and board at the same time and you will have a nice shiny solder joint, this means it didn't get too got and you got good flow from the flux.
A nice tip for holding the pins in place to solder --- u could insert them into the Arduino holes then stab the other long ends into a piece of foam like packing foam. Or styrofoam. I sometimes use a kneadable eraser for holding the pins too. Just mentioning in case it helps you or anyone who reads.
Considering this is a final assembly, It would probably be easier to solder a wire under the header on the Arduino from Aref to 3.3v rather than try to put two wires in a crimp connector.
yeah that's a really good idea, funny how you can miss something so obvious! Ill have to redo it with that method. thanks for watching and thanks for the advice!
LoL, before I clicked on your profile I stumbled across your channel and thought you were some smart pot head growing weed! Good job explaining it, easy to follow.
Dang!!! I wanna build a greenhouse and automate the heck out of it. When you get this all setup please share a imgur link or somethign I really want to see it.
This is great. I am planning to build a cooling system for my heat frame box that I use for germinating seeds before planting. They need to be kept at a certain temperature and this will be just what I was thinking about.
Wow amazing video. Well made. Very well explained. I was thinking of making one so my fan can turn on when heater is on and fan off when the heater is off.
I don't need to be in the giveaway, just wanted to say that you've made a nice and smooth video. Easy to listen to, and you've covered a lot of stuff. I've subscribed.
Would be cool to make for a kitchen exhaust fan, or with my compact fluorescent set up, or for use in a terrarium. New to Arduino and coding so I will be checking out more of your videos.
Depending on where you want the fan and where you put the sensor, and considering the space available and size of your cooking area. I would just stick with the temperature sensor in a good place and then adjust your temperature range for the ideal setting. Multiple sensors would be cool also; thinking a humidity sensor would be suitable. Not knowing much about the air quality sensor, I wouldn't know what parameters you would want to trigger the fan at.
Nicely done.... why not just solder some leads streight to the temp probe.... and skip the dupont and headerpins.... or even just plug the legs of the probe streight in to the dupont connector? On the board side the dupont makes more sence... but that just me :)
Good design mate. Not bad at all. Probably agree with Zarouszz. I am very fussy with Ac (I'm a 220er). Don't worry about the prizes for me (foreigner anyway), but that is very cool of you. Don't see small peddlers doing that often... Puts a bit of faith back in humanity as far as im concerned to well done bud./ Ill keep watching as a result of your kindness
It made me relax when you added heat shrink I hate people who leave this shit exposed. I don't get it heat shrink is cheap so just buy it. Although I would not have used a 150v fan I would have used a 12 or 9v DC fan
Thank you so much sir for the tutorial.. I want to make it for my school project. i.e temperature to control the speed of the fan. Please requirement for speed.
Hi! I'm strugling to grow some of my plants. Building some automated control will maybe help to understand what my greens are going through and maybe fix it. Nice 'hack' btw, keep going :)
Hi. Another great video! This is a great project as always! Unfortunately I do live in the UK and would be prepared to pay shipping but I would love to enter the give away. I would make a small weather station to feed data back like wind temperature, wind speed and more.
Very interesting project👍 BTW we have a plan, by using the ECT sensor from a car (fluctuate voltage will be availabe from 0.9 to 3 volt), to trigger the 3/5 v relay module, so it switch on/off a mass signal to a 12v fan relay. Is it Possible??
I have gone through this video and found to be useful to me; Thanks for this presentation which has taught me in detail about arduino with temperature sensor. I would like to have a presentation by you using the DHT11/22 sensors to sense the humidity and temperature and to drive external circuits of exhaust and sprinkler for my kitchen garden green house.Hope my request will receive your kind attention.
Hello, Thnx a lot for your great RU-vid, It means a lot if you share what you’re good in, so we can learn from each other. I hope you have time for a small simple question. Is there power on your relay coil when the NO contact is closed (when you’re hooked up fan is on) like a standard relay or does it gets a pulse each time you switch on and off you’re fan? Greats Bart
Hi, I found your nice ventilator system, which is practically what I want to built; however, the use of the ventilator is slightly different: I have in my central heating system in the house (a.o.) a vertically positioned radiator. The top of the radiator is about 50cm under the ceiling, consequently the heat builds up above the radiator. On top of that I have n old house with wooden beams supporting the ceiling which make the heat stay put between the beams. I have bought 2pcs 'be quiet' ventilator s12V, and want to make the system more or less similar to what you made. A temp sensor should respond at 40°C or so and blow the heat into the room. The ventilators are with 3 wires and it would be nice to have them start slowly (at half speed) and keep them running at half speed if the high temp setting can be maintained at that moment; if the temp runs over the high temp setting it should switch to full speed. I do realize this is quite something, but if it works, most likely more people can make use of it because I believe in the end it saves money when you can enjoy the (expensive) heat in the room instead of creating a warm ceiling. regrards, Tom
So here my question, is that fan can reduce the temperature from the sensor? Sorry for my bad english. Pls answer, because i have a project seems like this i wanna know if the fan can refuce a temperature.
there are links in the description to buy the three parts. youll have to provide the fan you would like to use. Also there are links in the description for the program and drivers, Thanks for the sub and watching the video. Dont buy anything yet. because im going to randomly pick 2 people from the comment section and mail them the parts! You might win! ( do you live in the usa? )
Techplant Silly me, just seen the description. How cool and yes I live in the US. Also just watched your succulent video, good stuff man. Enjoying the videos. Fingers crossed for the win.
I'm trying to do something similar, except that instead of a fan its a cooler for a diy minifridge. i cant get the arduino sketch to upload. would you be able to look at the errors and see whats wrong. ive never worked with arduinos so im not sure what im looking at
I'm trying to make a incubator controlled by an arduino. But I want to control the humidity as well using the dht11 sensor. Could someone guide me to a similar video? P.s: I don't want to use an lcd screen.
@@TechplantChannel i was confused with the "serial9600" haha i thought it was only for the motors hehe. Btw, i want to use it as an incubator for my future poultry hehe thanks a lot from ph :)
Great video. It's old as hell but I try it anyway. I bought all the parts and put everything together. But my temperature reading in the monitor goes down when I apply heat. The base temperature is 27.27 F. And even if I uncomment the Celsius line and comment the Fahrenheit line, I will still get a reading of 27.27 F. What did I do wrong?
Can I have a relay turn on at 40 off at 45 ( heat) then have a relay on at 55 off at 50 to open a vent then one on at 60 off at 55 for a fan. Exc. but just one temperature sensor. Multiple heating and cooling stages is what I’m after
@@benfriel12 yes you would just read from the same sensor and use some if statements in the code to check if the reading is in the range and activate the specific relay or relays you want only one sensor is needed for this
Hi, I really like your video! I would like to create something similar for my 3d printing hobby but I want to use a DS18B20 sensor that has data, Vcc and ground pin. How should I hook it up? would it work with your arduino program?
This is awesome. Would you be interested in tutoring through a small similar project with an Arduino, thermistor, and heating element? I'd be willing to pay for a session or two.
as many analog input pins as it has, i think you could do 8, they would have to share the voltage pins tho. you might have to do al ot more math. Im not really sure
in your script youll just set a timer to turn it on every 4 hours and run for 10 min, it doesnt need the temp sensor. maybe ill make a video about this
this video is really helpful and I will be grateful if am selected for the giveaway. I want to regulate the temperature of hot water inside a boiler tank that will trip at 75 degree celsius and pick up again when the temperature drops to 45 degree Celsius
I think it would be way to high for a beehive, but you could use any fan in this setup just have to find a lower RPM. Would this keep your beehive cool in the summer? that sounds like a really neat project!
You will never have 240 unless your bringing two hot lines in which you wouldn’t do with this kind of thing, your dryer and stove are 240 which is actually 208v so you don’t have to worry about that. Also regardless if it’s ac or dc it doesn’t mater what wire to connect the relay on AC doesn’t go in both directions current travels in one direction it’s about making a complete circuit. Dc can be switched on both the positive and negative, it all depends on if your circuit is sinking or sourcing
OMG! @5:10 why do you cut towards your fingers with a razor! I learned not to cut anything in the direction of any of my extremities when my dad gave me a brand new knife at 12 years old.. (And extremely sharp) He promptly took it back when he saw my finger with its tip missing.. yeah yeah, say what you want, my dad taught me allot that many other dads don't even do. My point is, DONT make a howto video where you use a razor cutting towards your finger that is less than a inch away.
I think youll need some kind of digital to analog converter. If you have a raspberry pi you can use it with that, but youll have to wire stuff up a bit different
