  • A sensor concealed in the grain

    Controlling the conditions of stored grain is the mission of these intelligent sensors

Agricultural sensors may be of great help when monitoring not only sowing process or harvesting maintenance, but also when storing seed recollection. That´s the case with BeanIoT, bean-like plastic devices with the size of a thumb which are thrown into grain silos in order to monitor its condition during the time they remain stored.

How do they do it? Each plastic bean features inbuilt humidity sensors, gyroscope, electronic compass and Bluetooth. Thanks to all those components, it can measure temperature, moisture, air quality, altitude, gas levels (including CO2) and the movement of the grain inside the silo. When BeanIoT sensors detect unusual values, they send a feed to a smartphone. The rest of the time they remain dormant in order to save energy. They charge wirelessly and, according to their creator, the battery lasts for 14 months.
