Description: 1. The HC-SR-04 Ultrasonic Distance Sensor Module is a versatile IoT component that utilizes ultrasonic waves to determine distance, making it ideal for various applications including obstacle detection, room occupancy sensing, and automated door systems. 2. This module operates on the principle of Echo Location; it sends out 8 bursts of ultrasonic sound at a frequency of 40kHz, then listens for the returning echo to calculate the distance between the sensor and an object. 3. Featuring a range from 2cm to 5 meters, the HC-SR-04 is widely used in projects where precise distance measurement is essential. It provides high accuracy and reliability with a measuring error of less than 3mm. 4. The sensor module includes an amplifier circuit to amplify the received signal and filter out noise for improved sensitivity and stability. This results in more accurate distance readings even in noisy environments. 5. With simple interfacing, this ultrasonic sensor can be connected easily to a mic
