Internet of Things as an element of the frost protection system in orchards

Abstract Frosts cause serious damage to fruit and vegetable crops. In Poland, temperature decreases, the occurrence of inflow (advective) frosts most often fall during flowering period, i.e., in a phase extremely important for development plant. For orchards, this causes inflorescences early trees (cherries, plums certain varieties apple pear trees) freeze. A modern idea reducing frost losses orchards is heat air with mobile heaters. Protection by these machines consists passing using an agricultural tractor rows or shrubs heating mixing air. The problem that farmers may encounter awareness when exactly such weather condition occurs their orchard. Weather forecasts are not detailed usually apply entire region. Dangerous declines below critical minimum can occur locally also conditioned geographical location terrain diversity. aim article present measuring system allows construction individualised model taking into account unique shape orchard surface. made Internet Things technology long-range radio communication protocol LoRaWAN. Data from distributed measurement sensors processed on network server displayed as final application. task monitor current situation notify farmer need initiate protective procedure. operation supports efficient use machines. facilitates areas lowest temperature, well provides feedback changes inside treetops caused passage heater.
