Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic waves, in particular to an ultrasonic sensor testing device. Background Art

[0002] Ultrasonic sensors convert ultrasonic signals into other energy signals (usually electrical signals). When ultrasonic waves strike impurities or interfaces, they reflect significantly, forming a reflected echo. When they strike moving objects, they produce a Doppler effect. Home lights can also be controlled using ultrasonic sensors, so it's necessary to test whether the ultrasonic sensor's trigger value meets certain requirements within a specified distance. Currently available testing devices are complex, requiring large, non-interference testing environments. Alternatively, the devices themselves are bulky, complex, and expensive. Therefore, it's crucial to develop a simple, low-cost ultrasonic sensor testing device. Summary of the Invention
