Alarms & Monitors

Sensaphone is a market leader of affordable, easy-to-use devices that monitor your greenhouse, hoop house, garden center, nursery building, home, business, vacation home or computer room for problems such as power outages, temperature fluctuation, water damage and intrusion. In the event that one of the aforementioned issues occurs, the Sensaphone will autodial pre-set telephone numbers to notify you of the occurrence. Remote access also makes it possible to call in at any time with a touch-tone telephone to check the status of all monitored conditions and to make program changes. Sensaphone allows you to detect problems before they become disasters.
