Description

technical field [0001] The invention belongs to the fields of agricultural intelligence and environmental protection, and relates to a self-driven agricultural internet of things wind speed sensor based on a friction nanogenerator. Background technique [0002] In addition to natural light, heat, water, and air that are beneficial to agricultural production, wind is also one of the environmental factors of agricultural production. Normal wind is very effective for agricultural production, and moderate wind speed plays an important role in improving the environmental conditions of farmland. So measuring wind speed and direction will be of great help to agriculture. Therefore, it is necessary to monitor the wind speed in a timely manner. The sensors used for monitoring today are mainly wind speed sensors based on the principle of heat transfer or differential pressure. They are important equipment for wind parameter measurement in agricultural climate automatic monitoring stat...

Problems solved by technology

[0008] In order to solve the problem of measuring agricultural wind speed and collecting it and converting it into frictional electricity for easy storage, the electricity for wind speed detection comes from the measurement itself. The AC signals of different frequencies generated by the nano friction generator can measure and calculate the wind speed, and can store the electric energy to supply power for other sensors, thus solving the problem of self-power supply or self-drive of the sensor system
