the project is to create the device which will have one 16x2 lcd, 3 or 4 keys, 3 relays, 1 dht11 temperature and humidity sensor and that device is going to be placed in dehumidifier facility for dehumiding wooden materials. when device is turned on it is neccesery to set the desired value for humidty. as well as desired value for temperature, for example, if the set humidity is 20% but in the same time reall humidty is above that value, the relay should be turned on, if the humidity drops under 20% then switch of relay, also at the start there shoudl be set desired temperature, eg. if set temperature is 20 degrees and the temp is bellow that switch on relay, when temperature gets to desired value switch of relay, it is important to be able to set the desired values for temp and humidity using keys, of course this is al not so complicated, but there is another part, when machines work and dehumidify the wood, at some moment the humidity will drop to the desired level... if that humidity drops lower than desired level for lets say longer than 10 minutes... for example is humidity is at 19% for more than 10 minutes... then this new value should be set as the new DESIRED level, the new value should owerride initialy set value so any new lower value should owerride previous, if drops to 18 new value is 18... or 17, 16 etc, also this should be corelated with the temperature, as the humidity goes down, new set value should go up. humidity goes down 1%, at the same time new set value for temperature should be +1, previous and +1, this cycle should repeat as long as the humidity reaches 6%, and at that moment everything should switch of, print "process finished" at the display and switch on the third relay, also... it is neccessary to be able to set that variable values... their steps... for example to be able to reconfigure that when humidty goes down it does not set temp higher one whole degree but half degree instead etc. Just to be understand When device start we must set temperature, humidity, time x (when humidity is reached and below seted value in minutes eg. 0,1,2,3,4,5,6,7,8......60), step for temperature rising when hummidity is ok and time is passed eg. (+0.5,+1,+1,5,+2,+2,5,+3.....5), humidity for end of process eg. (4,5,6,7,8,9,10,11.....20).
Hello dear
i have experience in designing electronics circuits and can make your project. I will make your project practically on breadboard and will provide you circuit, code, PCB design and a video of working prototype. If you wish we can discuss in chat.
Hey I can help you with this but you have to understand that I will only provide you with circuit schematics, layout and the arduino code that will be error free.
You have to manufacture the product by yourself but i will help you in testing and give you expert advice. Also i am flexible to work more for you.
I am bidding low to capture the market at freelancer.
I am very much expert in embedded related stuff.
Good Day!
Greetings,
I have good experience with Arduino, Control Loop Programming (which is what you need here), DHT11 sensor. In fact I recently made a temperature & humidity control system for a lunch box using DHT11 (not uploaded in the portfolio yet).
In short I think I can assist you with this project here. Please have a look at my profile for details of my related work.
Look forward to hear from you.

I assure you, if you assign your project to me, you surely gonna work with me in future.
Note:
I also provide Online or Recorded Video Tutorials to the online students for Electrical Engineering Subjects.
hi i am an electrical engineer. i have vast experience related to micro controller and its programming. i have done many embedded system projects. i have hardware experience regarding Arduino. let me know if you are interested. we can discuss further on chat.
Hello
I have got your job posting “Arduino wood dehumidifier electronic” and I am very much interested to work in your project. I am a circuit designer and have more than 5 years experience of working with the embedded systems(Arduino ,ARM processors ,PIC microcontrollers,All types of sensors and actuators). i have done tons of similar projects So, I think you’ll find, I have the skills you’re looking for. For more on my skills and successfully finished projects, please have a look on my Profile and Portfolio.
I have all the components available here with me so i will develop a working prototype according to your specifications and then send you the code and schematics so things will work for sure.
I am always available on Email and Skype. Please have a voice or video chat if necessary. I will be available more than 60 hours per week and able to start your project as soon as possible according to you.
Thank you for your consideration,
Best Regards,

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. I can help you with your deal and since im new one here I can do it cheaper then anybody.
(autopromotion^))
Do you need this device to be done using arduino+modules connected with wires or own designed one? I can do both variants, prototype, manufacture. Lets talk.
Hello,
I have experience in arduino, DHT11 and relay controls. These are the basic requirements for your project. I have also experience in algorithm development which will be put into good use with this complex process of wood dehumidifier.
The following are the key things that I propose :
1. All the key configuration will be on-board through keys
2. There will in-built hysteresis to avoid frequent switching on and off of heavy equipments
3. Live status of the process displayed.
Additional feature with additional cost:
1. I can provide you an android app to control and monitor the whole process from your smartphone.
2. All the configuration can be done on the smartphone and process initiated and monitored.
Thank You
Your hardware:
- LCD 16x2
- Some keys
- 1 DHT11 for temperature and humidity sensing
- 03 relays
+ 1 for heater
+ 1 for dehumidifier
+ 1 is not described
- Arduino board as controller
Working procedure
1> Using key to set initial desired temperature and humidity
2> Arduino control two relays (heater and dehumidifier) On/Off to reach those desired values
3> When humidity drop below desired value more than 10 minutes; change desired humidity and temperature to new values
4> The changing step need to be set by user (using keys)
(detail of 3 and 4 need to clarify when start)
You'll receive
- Guidance to setup hardware system if need
- Some basic Arduino sketches for testing system functional
- Complete working sketch
Payment
- No upfront. After finishing
Also provide custom PCB service if you need
Hi,
I am interested to work on this project. I have read the description and this is what I can do within few days. I will take 8 days to prepare this system and I will provide the compiled and tested code.
Let me know your view. If you are interested, then kindly reply to this proposal and if you are having any query, then please feel free to contact.
Thanks.
