ATM environment alarm system

In ATM there are a risk of excessive dust or smoke.
•
dust primarily in the wood workshop but also in the welding cabin.
•
smoke in the metal workshop, primarily from welding and use of angle grinder.
Because it is difficult to detect while working as you get used to it and is difficult to evaluate what dust/smoke levels are harmful ATM would like to put up environmental monitoring systems in the wood workshop and welding cabin.
At the same time the system should warn before we accidently set of the DTU fire alarm system as a false alarm could call unwanted attention to ATM.
