Ultrasonic sensor

Due to the strong directivity of ultrasonic waves, the ultrasonic transmitter emits ultrasonic waves in a certain direction, and returns immediately when it encounters an obstacle on the way. It is easy to calculate the distance between the launch point and the obstacle through the principle of time difference and the speed of sound. And because the ultrasonic energy consumption is slow and the distance in the medium is long, it is often used for distance measurement. The ultrasonic sensor emits ultrasonic waves into the air to detect the reflected waves from an object. Ultrasonic sensors are widely used in, for example, anti-theft alarm systems, automatic door and window opening and closing systems, car reversing sensors, and liquid level detectors.

With the help of advanced technology and years of experience, BESTAR Sensors Co., Ltd.has developed various types of ultrasonic sensors with small size, light weight, high sensitivity, low energy consumption and superior performance to choose from.
