The HC-SR04 Ultrasonic Module is a rangefinder that can be used to measure the distance to an object. It is often used with the Raspberry Pi as it is easy to connect and can take accurate measurements over a wide range of distances.
The HS-SR04 ultrasonic module is an optimized design based on the traditional HC-SR04 ultrasonic module. It retains the same functionality and size as the HC-SR04 but has several detailed optimizations for improved performance. This module offers stable performance, precise distance measurement, high accuracy, and a small blind zone.
