JAVELOT is a connected thermometry solution monitoring the temperature of stored grain from a smartphone or computer. The solution has been designed to be as intuitive and simple as possible : it is wireless, 100% autonomous and does not require internet connection on site. It is suitable for flat storage sites, regardless of their size or geography. It is possible to follow the evolution of the temperature and to send back alerts to the storers, as well as to offer a traceability of the grain during the whole storage period.
