Ultrasonic distance measuring circuit diagram: Type 4Y2 distance measuring alarm control special integrated circuit, which can be used to assemble distance measuring alarm control electronic products. It uses the principle of ultrasonic distance measurement to detect obstacles in front of the ultras

Due to the strong directivity of ultrasonic waves, slow energy consumption, and long distances in the medium, ultrasonic waves are often used for distance measurement. For example, rangefinders and level measuring instruments can be realized by ultrasonic waves. Ultrasonic detection is often quick,

‍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

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
