Ultrasonic sensors are widely used in robot obstacle avoidance systems. Based on the ultrasonic ranging principle, a parallel ranging system is designed. The hardware composition and software realization method of the system are introduced. Aiming at the phenomenon that multi-sensor parallel ranging

For many years, ultrasonic sensors have been widely used in passenger cars. For example, ultrasonic parking system can help vehicles detect surrounding objects when it is parking at low speeds. In addition, kick-opening the trunk and intrusion detection alarm are two emerging applications of ultraso

Reversing radar, namely "reversing collision avoidance radar", also called "parking aid", is mainly composed of ultrasonic sensors (commonly known as probes), controllers and displays (or buzzers). The system adopts the principle of ultrasonic distance measurement sensor. The ultrasonic probe on the

Robot autonomous positioning and navigation of ultrasonic level sensor is simple, but it needs to be based on the combination of map data + algorithm to achieve true automatic automatic navigation; robot navigation can be divided into three parts, including positioning, mapping and motion control. W

As the name implies, the aircraft model is a recyclable model made to imitate the shape of a spacecraft. It belongs to the aerospace model. In the competition rules formulated by the International Aviation Federation, it is clearly stipulated that the aircraft model is heavier than air and has a siz

Ultrasonic sensor is a sensor that can measure distance and position by sending and receiving ultrasonic waves. Since the sunroofs of automobiles are almost transparent, various sensors based on optical principles cannot measure. The ultrasonic sensor can send out ultrasonic waves and receive echoes

Industrial ultrasonic sensor has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, which can become rays and propagate directionally, long range ultrasonic sensor has a great ability to penetrate liquids and solids, especially in soli

In recent years, with the development of mobile robots, unmanned vehicles and drones, the demand for obstacle avoidance ultrasonic sensors has increased. Traditional ultrasonic sensors that can be used to avoid obstacles include millimeter wave radar, lidar, binocular vision sensors, ultrasonic sens

AGV is the abbreviation of (Automated Guided Vehicle), which means "automated guided vehicle", which refers to equipped with electromagnetic or optical automatic guidance devices, which can drive along the prescribed guidance path, with safety protection and various mobile transporter with loading f

‍By using high-frequency sound waves to detect the position and distance of objects, ultrasonic sensors can usually work in the absence of other types of sensors. They work like echolocation in bats or dolphins. These Industrial ultrasonic level sensor emits sound waves (inaudible to humans) and the

How do ultrasonic sensors handle noise and interference? Any acoustic noise at the frequency received by the long range ultrasonic sensor may interfere with the sensor's output. This includes high-pitched noise, such as sounds generated by the click of a whistle, safety valve, compressed air, or pne

System function overview and block diagram This design uses MCS-51 single chip microcomputer combined with digital chip and analog circuit to complete the detection and automatic control of water level. The basic work flow which the host sets the liquid level of itself and the slave through the keyb

Since the birth of the sensor, the ultrasonic sensor has become the most important infrastructure in the digital society because it can help humans turn information that was once unknown and difficult to judge into easily accessible and more accurate data. In 2011, the founder and venture capitalist

Piezoelectric films are widely used because of their excellent performance. Piezoelectric thick films can be used to manufacture a variety of micro devices, such as micropumps, ultrasonic motors, resonators, pyroelectric thick film sensors, thick film actuators, micro-energy pickups, etc. 1. Hydroph
