Topic: Arduino as protection for heating system  (Read 450 times) previous topic - next topic


 Hello guys,  I want to build a protection module  using arduino uno   for a heating system that uses coal.

In case the water trough the system goes  over 70 degrees Celsius  or 3.5 bars pressure  I need arduino to  power a buzzer as an alarm..   

I have the  arduino uno starter kit that comes with 2 buzzers but I think they are too small.

I think I will need an adjustable pressure switch,  a temperature sensor, power supply and a bigger buzzer.

What do you think about this??
Can you recommend me  some parts that work well with arduino uno?
