In daily production and life, ultrasonic ranging sensors are mainly used in car reversing radar, robot automatic obstacle avoidance walking, construction sites, and some industrial sites such as liquid level, well depth, pipeline length and other occasions that require automatic non-contact ranging.

Ultrasonic sensors are sensors developed using the characteristics of ultrasound. Ultrasonic ranging sensors are sensors that convert ultrasonic signals into other energy signals (usually electrical signals). Ultrasound is a mechanical wave with a vibration frequency higher than 20kHz. It has the ch

The SMD buzzer can be called a signaling device found in electronics. Generally, SMD buzzers are used in home appliances and automobiles. It also consists of multiple switches and sensors connected to a control unit. Devices usually determine which control button is currently available. SMD buzzers
