What Is Ultrasonic Distance Measurement?

Ultrasonic distance measurement
The ultrasonic distance measurement sensor adopts the ultrasonic echo distance measurement principle and uses accurate time difference measurement technology to detect the distance between the sensor and the target. It uses small angle and small blind area ultrasonic sensors, which have the advantages of accurate measurement, non-contact, waterproof, corrosion-resistant, and low cost. It can be applied to liquid level and material level detection. The unique liquid level and material level detection method can ensure stable output when there is foam or large shaking on the liquid surface and it is difficult to detect the echo. Application industries: liquid level, material level, material level detection, industrial process control, etc.
24GHz radar
The 24GHz radar sensor uses high-frequency microwaves to measure the speed, distance, direction, and azimuth angle information of the object. It adopts a planar microstrip antenna design and has the characteristics of small size, light weight, high sensitivity, and strong stability. It is widely used in intelligent transportation, industrial control, security, sports, smart home and other industries. On November 19, 2012, the Ministry of Industry and Information Technology officially issued the "Notice of the Ministry of Industry and Information Technology on the Release of the Frequency of Use of 24GHz Frequency Band Short-range Vehicle-mounted Radar Equipment" (Ministry of Industry and Information Technology No. 548 [2012]), which clearly proposed 24GHz frequency band short-range vehicle-mounted radar equipment as the specification of vehicle-mounted radar equipment.
