The SSMK-1 is a professional indoor grow room smoke detector designed to be used with the Croptiva controllers. When used with the controllers, the smoke   detector will constantly monitor the growing area for smoke. The Croptiva smoke detector has been designed to be sensitive to even small amount of smoke. If the SSMK-1 senses smoke within the area, the controllers can be programmed to trigger a local audio-visual alarm, and to send SMS alert messages using the free Croptiva app. The Croptiva controllers can also be set-up to automatically shut-down devices within the growing area such as fans, AC units, Dehumidifiers, Lights etc.
