WIRELESS SYSTEM FOR MONITORING GRAIN STORAGE PARAMETERS USING ULTRASONIC VIBRATIONS TO TRANSMIT ENERGY AND INFORMATION Russian patent published in 2023 - IPC A01F25/00 

FIELD: grain storage.

SUBSTANCE: systems for remote monitoring of grain storage parameters in a grain mound used in floor grain storage warehouses. The system for monitoring grain storage parameters contains a master device, slave devices located inside cylindrical steel perforated housings connected to each other by thread, one end of the outermost slave device has acoustic contact with the master device. The master device contains an autonomous power supply, a first microcontroller, a radio module, and a first ultrasonic transceiver unit. Each slave device contains a second microcontroller, a digital sensor system, a second ultrasonic transceiver unit, a converter of ultrasonic vibration energy into electrical energy, and an electrical energy storage device. A digital sensor system is a “system in a package”, for example BME680, which contains sensors for temperature, humidity, volatile organic compounds and atmospheric pressure; the radio module is a device for transmitting and receiving information over an ISM radio channel.

EFFECT: system allows to measure temperature, humidity, and the concentration of volatile organic compounds in the air in the intergrain space at many points of the grain mound along its entire length and/or width.
