Comparing 2 temp sensors

Other Hardware Home Automation
1

Hi all,

I am new to arduino with no programming experience.
I need to compare two temperatures and output a relay on a specific condition.

Lets say that i have two temperature sensors, T1 and T2 and i want to output a relay when T1 e higher than T2.

I think this is relatively easy to accomplish, although i have no experience in programming.

Can anyone help?

Kind regards,
Rodrigo Catarino

Sorry, the temperature sensors i am trying to use is the DS18B20

What you're hoping to do is pretty trivial. Start with the examples here: Examples.

Google should find you plenty of other examples/tutorials using the DS18B20 with an Arduino.

If you're asking for someone to do this for you though, ask the moderators to move this thread to Gigs & Collaborations but expect to part with a little cash.

Hello,

Lets say that i have two temperature sensors, T1 and T2 and i want to output a relay when T1 e higher than T2.

I never try compare 2 temperature sensors. Check this : [u]Controling 2 relays (SRD-50VDC-SL-C) depending on 2 temp sensors (DS18B20) - Programming Questions - Arduino Forum
