Many farms are already using the latest technology. So drones became assistants in tracking the economy and collecting various data useful for farming. But one charge is enough for even the best quadrocopters for a maximum of half an hour of flight. And engineers from the University of Washington decided to put sensors on the bees. These \ For bees, experts have created miniature backpacks with sensors. In the hives, they put stations transmitting data and charging the device wirelessly. The GPS signal spends a lot of energy, so instead of these transmitters, several antennas were used, sending signals to the electronic \ Bee backpacks collect information about temperature, light, and humidity. The battery and sensor memory lasts about 7 hours. Once a bee returns to the hive, the information is sent to farmers, and the backpack starts to charge. The only minus of the system is the inability to control the behavior of bees. But this method of collecting information is simple and inexpensive for farmers. It exceeds the capabilities of drones, which are very noisy and quickly discharged.
