![Trolmaster MBS-SD Smoke Detector](http://dieppehydroponics.com/cdn/shop/products/MBSSD_{width}x.jpg?v=1645022354)
The optional Smoke Detector (MBS-SD) can alert the user to smoke within their growing area at ALL TIMES. Up to 5 smoke detectors can be connected to a single Hydro-x controller. If ANY of the smoke detectors determine there is smoke in the area, the user will receive a user-alert on their phone to alert them to the potential problem BEFORE the problem gets out of hand.
