Description: 1. The HC-SR-04 Ultrasonic Sensor is a versatile and cost-effective solution for implementing short-range distance measurement and obstacle detection in IoT projects. Available in bulk packs of 25 sensors, it's an ideal choice for large-scale applications or educational purposes. 2. This sensor utilizes ultrasonic technology to emit sound waves that bounce off nearby objects, measuring the time taken for the echo to return and calculating the distance accordingly. Its measurement range is from 3cm to 6 meters (approx.), making it suitable for various IoT applications. 3. The HC-SR-04 sensor consists of four components: a transmitter, receiver, trigger, and an output module. It features a waterproof design, ensuring resistance against rain and splashes, which makes it suitable for outdoor use as well. 4. With a simple digital interface, this ultrasonic sensor is easy to connect with microcontrollers like Arduino or Raspberry Pi, enabling users to program custom applications to read
