Im looking for an arduino uno R3 board to take the average temp and humidity of a room from (3) AM2311A sensors and use that data to turn on or off a humidifier, dehumidifier, heater and a cooling fan via an 8 channel dc 5v relay when the data drops below or rises above specific temp and humidity levels. I would also like to put a fourth AM2311A sensor in the ducting that's blowing the preconditioned air into the room and id like to have that data displayed on a SunFounder IIC I2C TWI Serial 2004 20x4 LCD Module . also on the display would be current temp and humidity average from the 3 modules in the main room, and characters flashing on the bottom row when relay is triggered and solid when not triggered (H when heating, C when cooling, D when dehumidifying and Hu when humidifying.)

Hi and good morning, I've realized a greenhouse LED control system that's quite close, it uses ESP's and has a WEB interface. However also an UNO R3 could be fit; my only concern is that there will be a lot of wires that could have false contacts, especially in an hostile environment, hence making the system unstable. Therefore my advice is to produce also a PCB, that's not expensive, with an Arduino Nano/Micro and with swappable connectors so if a sensor fails you can easily replace it. Also you'll get a working system with no issues with cabling, soldering etc. I Already have the sensors of temp/humidity and I2c display (albeit is 20x2 lines) , also I have optoinsulated relay modules so it will be easy to realize a prototype. If you deem the proposal interesting we can discuss your needs in order to be 100% sure that I've got all the requirements, also beware that realizing the PCB, mount and test it will require time. Cheers, Alex. p.s. Delivery expenses and price of parts are not part of the bid.
