NEW WatchDog Critical Alert
DESCRIPTION: The WatchDog Critical Alert is a new, low-cost, remote temperature monitor with cellular communications. Set it for frost (or any temperature) and receive an alert by phone call or text message. The unit also has a relay to trigger an external device, such as a sprinkler system, automatically. Since there is no computer required, it is easier than ever to protect your crop from frost.
