NOS-2VT Frost warning device for early potatoes
Description
NOS-2VT is optimized for use as a frost detector in the cultivation of early potatoes and other crops cultivated under cover. The temperature is measured at two points directly where the cover rests on the crop.
In daily use, only a cell phone is required to query current measurement data, receive warnings and switch electrical consumers, e.g. pumps, on and off.
Functionality
The system can be used in three different ways simultaneously:
Warning mode
Using the supplied software, the warning thresholds for the two temperature sensors can be set separately. If these thresholds are exceeded or undershot, an SMS warning message is immediately sent to up to 4 cell phone numbers. If desired, the warning can also be repeated up to 4 times, or additionally sent by email, the text of the warning message can be freely formulated.
Info mode
The current wet and dry temperature and the status of the internal relay can be queried at any time by cell phone (password - SMS). The current voltage of the battery is always sent automatically.
Switching mode
Also the internal relay can be switched at any time by cell phone (password - SMS). Relay: changeover contact max. 250 VAC, at 2A. Optionally, the switching operation can also be automatically linked to the exceeding or falling below of a warning threshold, thus a sensor-controlled automation can be realized with the Now_SMS device.
