Abstract In smart agriculture, lots of sensors are widely distributed in farmland with a complex environment. The methods of powering these sensors have attracted extensive attention, of which harvesting the breeze energy abundant in farmland is a good way. Herein, the triboelectric nanogenerator with blade‐enclosed structure (BE‐TENG) is proposed to enhance the durability and robustness. The device achieves a low start‐up wind speed of 1.5 m/s due to the structure based on the horizontal axis wind wheel and can output an open‐circuit voltage of 360 V. Importantly, after 10 hours of continuous operation, the voltage signal of the BE‐TENG has almost no attenuation, and its output performance can maintain stability even in a high humidity environment of 90%, showing strong durability and robustness. Experiments show that under breeze conditions, the BE‐TENG can drive almost 600 light‐emitting diodes and successfully power a soil temperature sensor. In addition, it can drive a hygrothermograph in a simulated rainfall environment, realizing the monitoring of ambient temperature and humidity. This work can convert breeze energy in farmland into electricity needed for agricultural sensors, which provides a new strategy for distributed energy supply required for smart agriculture.
