The GrowAlert Wireless Magnetic Sensor can be used to detect when doors or windows are opened.

It is easy to install and will fit most doors and windows. Each GrowAlert Wireless Magnetic Sensor connects to the GrowAlert Base Station wirelessly. When triggered (by unauthorised opening of a window or door), the Auto-Dialler Alarm System sounds a loud alarm (if desired) and automatically telephones 3 pre-set numbers to provide your grow room, greenhouse, garage or garden shed with maximum protection and you with peace of mind.
