I want to build a simple heat sensor that will sound a alarm when the temp sensor reaches a specific temperature. I would prefer to using Arduino but will look at any suggestions you have. I have 10 of these plans I need for 8 different Arduino sensors. I will pay per plan, I want the plan written so I can go buy (Arduino or other) parts and assemble and make work these sensors.

I have built many arduino temperature and humidity sensors with triggers. so sounding a noise with a threshold won't take very long. I hope I can assist you in your project!
