In the web portal, you can set whether you want to be alerted based on the Dew point temperature or based on the measured air temperature, and at what preset threshold this should be (adjustable between +5°C and -5°C). A routine running in the background of the web portal continuously checks if this threshold has been reached. Once this is the case, you as a grower will be called on your mobile phone and you will hear a computer voice reporting that one of your stations has issued a frost alarm. In addition, an email may also be sent to your mailbox containing the data of the station that issued the alarm, the value measured or calculated and the preset threshold for the alarm. The settings for the frost alarm consist of two parts:
After step 4 is completed and saved, this station is included in the frost alarm system. Then repeat step 3 and step 4 for the other stations that you want to include in the frost alarm system.
