WatchDog Pro Mobile Frost Alert

The WatchDog system will warn you in advance of frost conditions so you can take action. It is ideal for the care of your crops.


The WatchDog Pro mobile frost alert will warn you in advance of frost or when frost conditions are expected soon so you can take action. It is the ideal choice for your crop care.

When the temperature reaches the set limit, a phone call is made and/or a message is sent to a set number to alert the user. If this call is not answered by the user, the system itself will make another call.

The features of this mobile frost alert are as follows:

  • The system uses a SIM card to warn (via message and/or call) up to 4 telephone numbers of upcoming frost conditions.
  • Requires one 6-volt battery (not included).
  • Fully user configurable to set critical limits before alarming.
  • Temperature range: -30 to 55 ºC.
  • Accuracy: +-0.6 ºC with temperatures from -20 to 50 ºC and for other temperatures an accuracy of +- 1.2 ºC.
