Hello. I need assistance as im a newbie.

Hello

If you tell us any piece of your idea, or a basic description, it could be possible that someone to give you one or two advices.

I will try to help you if I can.

And welcome.

Hi. I'm a commissioning engineer and I write Plc software. What I'm trying to do is by use of a raspberry Pi, control my heating at home, via a web browser. So I need to incorporate a sensor. If I want to make it more user friendly I would also need to add 3 non latching push switches. One to increase temp, one to decrease temp and one to select either auto, override or off. Finally it would be good to change the led background colour from blue to red dependant on wether the temp set point had been achieved.

Phew!

Thanks in advance for any assistance.

Hi. Is raspberry pi is in the asignment? Or you have chose it by your self? Ithink you can do it with arduino. There is a shield and libraries for ethernet. ofcorse with Pi you can make nicer page design and add more functions later. But since you do not need usb or something like that. Then arduino may be ok.

As for sensors. You can use DS18B20 (datasheet:  https://www.google.lt/url?sa=t&source=web&rct=j&q=ds18b20&ei=V9n8VIHbJMrKOZv9gJgG&url=http://datasheets.maximintegrated.…)  temp sensors. They can be connected in paralell. So you do not need much pins for that.

Or use a humidity + temperature sensor. It depends on you. ass for color you can use PWM to fade in and fade out thous needed ones or just turn them on and off.

You could write this for any of the platforms mentioned however I feel the application is so simple that unless you specifically need WIFI or Ethernet control you would be better off with an Arduino as it's so much easier to program  than the SBCs. Other advantages would be that the Aduino is cheaper/uses less power and you don't need an SDcard to hold the code. If you need WIFI/Ethernet then trying to do this with an Arduino would really shift the economics and complexity back to the RPI/BBB

Thank you for your input.

Yes, I require wifi connectivity. This is so it can be controlled by my iPhone away from the house.

Much appreciated.
