1. Piezoelectric force sensor　　 Piezoelectric force sensor is a industrial ultrasonic sensor that uses piezoelectric elements to directly realize force-to-electricity conversion. In tension and compression applications, two or more piezo quartz crystals are usually used as piezoelectric elements.

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

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

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

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

The main purpose of ultrasonic transducers is to measurement and alarm. The design involves more content, mainly combining the single-chip control module, ultrasonic ranging module, buzzer alarm module and 4-digit digital tube display module. The core of this design is the ultrasonic ranging module.
