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

　　Ultrasonic transducer is a device that transmits and receives ultrasonic waves during ultrasonic testing. The performance of the probe directly affects the characteristics of the ultrasonic wave and the detection performance of the ultrasonic wave. The ultrasonic sensor is used in ultrasonic test

The formula for calculating the K value of the inclined ultrasonic transducer is as follows:　　 The K value of the inclined ultrasonic transducer sensor refers to the tangent value of the refraction angle. The mathematical calculation formula of the K value of the inclined probe is:　　K=tanβ=L (defect

Principle of piezoelectric ceramic transformer　　 Piezoelectric ceramic transformer is a new type of chip device that realizes low voltage input and high voltage output through the secondary energy conversion of electrical energy --- mechanical energy --- electrical energy. Its basic structure has ma

Factors affecting the normal operation of ultrasonic liquid level gaugeSeveral factors affecting the normal operation of ultrasonic liquid level gauge The effect of stirring on the ultrasonic level transducer.The on-site container often has stirring, and the liquid fluctuation is relatively large, w

Principle classification of measuring water flow The principle of measuring the water flow by the time difference method,at a certain distance upstream and downstream of the measuring pipeline, two pairs of ultrasonic transmitting and receiving probes (F1, T1) and (F2, T2) are installed respectively

The characteristic of this system is to use the single-chip microcomputer to control the transmission of ultrasonic waves and the timing of the round-trip time from the transmission of the ultrasonic waves to the receiving.Among them, only the wiring diagram of the front ranging circuit is drawn.
