drones in21stAt the beginning of the century ushered in the high-speed growth period, and gradually expanded from the * * field to the civil field. Nowadays, unmanned aerial vehicles have been widely used in many fields such as cargo transportation and express delivery, monitoring and measurement, environment and animal protection, emergency rescue, environmental testing, electric patrol line, aerial photograph surveying, agricultural plant protection, etc. WithInternet of Things technologyincreasingly mature, the current UAV development of the Internet of things technology applications more and more, in which sensor technology has played a very important role. application of UAV's Internet of Things technologyAccelerated Designaccelerometers are used to determine the position and flight posture of the drone. Like NintendoWiicontroller orIPhonescreen position, these smallMEMSThe sensor plays a key role in maintaining flight control. Memsaccelerometers have a variety of ways to perceive motion posture, and one type of technology can perceive tiny movements of micro-integrated circuits. This type of“Diving Board"motion alters the movement of the current in the structure, thus indicating the displacement change associated with gravity. another kind of accelerometer technology for the thermal convection technology, has several obvious advantages. it has no moving parts, but a“Hot Gas Regiment"the displacement to perceive the motion changes. This type of sensor is highly sensitive and plays a vital role in stabilizing applications such as car cameras and film production. by controlling the upper and lower motions and anti-vibration functions, the producer can capture the picture very smoothly. In addition, since these sensors have better seismic resistance than other products, thermal convectionMemsThe sensor has a perfect performance in the anti-vibration of the UAV propeller motion. Inertial Measurement UnitInertial measurement Unit combinedGpsis the key to maintaining direction and flight paths. With the development of UAV intelligence, direction and path control are important rules of air traffic management. the multi-axis magnetic sensor used in inertial measurement units is essentially a small compass with a very high degree of precision, which transmits data to the central processing Unit through the sensing direction, indicating direction and speed. Tilt Sensortilt sensor with integrated gyroscope and accelerometer for flight control system to maintain horizontal flight data. This is the most important stability monitoring application in the transport and delivery of fragile goods. these sensors and gyroscopes, combined with accelerometers, are capable of measuring subtle motion changes, allowing inclination sensors to be used in mobile applications such as gyro compensation for cars or drones. Current Sensorin drones, the consumption and use of electricity is very important, especially in the case of battery power. Current sensors can be used to monitor and optimize power consumption, ensuring the safety of battery charging and motor fault detection systems within the UAV. current sensor works by measuring current(bidirectional), ideally providing electrical isolation to reduce power loss and eliminate the chance of electric shocks damaging the user's system. at the same time, the sensor with fast response time and high accuracy can optimize the life and performance of the unmanned aerial vehicle battery. Magnetic Sensorsin drones, the electronic Compass provides critical information for inertial navigation and directional positioning systems. based on anisotropic magneto-resistive(AMR)Technology of the sensor, compared with other sensors have obvious advantages of power consumption, while the high precision, short response time and so on, very suitable for the application of unmanned aerial vehicles. The total solution provides a stable and compact package for the unmanned aircraft manufacturer with a mass data sensor. Engine inlet Flow sensorthe flow sensor can be used to effectively monitor the micro air velocity of the Power UAV gas engine. This feature can help the engineCpudetermine proper fuel-air ratios at specific engine speeds to improve power and efficiency and reduce emissions. many gas engine mass flow sensors use thermal technology to quantify mass flow using heated components and at least one temperature sensor. Memsthermal gas mass flow sensors also use thermal principles in the micro-metering range and are suitable for areas where weight requirements are high. with the continuous maturation and progress of technology, people's awareness of the application of UAV is deepening, the UAV is playing an increasingly important tool.
