Oneof the key components in vibration sensor testing technology, its function ismainly to receive the mechanical quantity and convert it into a proportionalamount of electricity. Because it is also a kind of electromechanicalconversion device, we sometimes also call it transducer, vibration picker, etc.
Adrone sensor can be defined as a system that is able to determine changes thatoccur in terms of physical or electrical variations as well as otherquantities. The sensor is then able to acknowledge this variation in the droneand act accordingly in order to ensure the proper functioning of the drone.
Biomass fuel is a high-density block orgranular fuel made of wood chips, bamboo chips, twigs, stalks and other rawmaterials, which is compressed and formed by high pressure and low temperatureby professional machinery and special technology without any chemicaladditives.

Photovoltaic tracker, also known as solar tracker, is the power device that keeps the solar panel directly facing the sun at any time, so that the light of the sun shines vertically on the solar panel at any time. Using this device tracker can significantly improve the power generation efficiency of solar photovoltaic modules.
SolarCells and Modules are the core components of photovoltaic power generationsystems, and their development level directly determines the development levelof photovoltaic power generation. Since the invention of solar cells in 1954,after more than half a century of development, there are currently a widevariety of solar cells, and their conversion efficiency has also beensignificantly improved.
