Wireless Alarm Manager
No landline? No problem. Protect your crop by monitoring greenhouse temperature remotely. This remarkably persistent device continues to send you text messages until the alarm condition is resolved. The Wireless Alarm Manager communicates directly with your environmental control, so when the greenhouse temperature is in alarm condition, or in the event of power failure, it sends a text message to as many as 4 cell phones to alert you.
