Introduction of HC-SR04HC-SR04 is a very popular sensor for measuring distance. It emits ultrasonic waves at a frequency of 40KHz. The ultrasonic waves travel through the air. If there are objects or obstacles in the path, it will bounce back to the module. Taking into account the propagation time a

Ultrasonic sensors are devices that convert ultrasonic signals into other energy signals (usually electrical signals) to measure distance from the sensor to the target object. Ultrasonic wave is a mechanical wave with a vibration frequency higher than 20KHz and it has the characteristics of high fre

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

Buzzers can be divided into piezo buzzers, magnetic buzzers and mechanical buzzers. This is classified according to how the buzzer works. Active buzzers can be used for different purposes, such as alarm clocks or timers. It can also be used for home appliances. The active buzzer market has rapid

There are two types of piezo buzzer, active buzzer and passive buzzer, each with its advantages. In this article, we will discuss the various benefits of using an active buzzer.

Piezo buzzers are also known as piezoelectric materials, and their shape can change, especially when exposed to various electric fields. A piezo buzzer material has an atom. The atom usually has a central nucleus made of multiple neutral charges, such as the positive charges. These charges are calle
