The ACEBOTT HC-SR04 operates on the principle of ultrasonic echo-ranging. The module emits a 40 kHz ultrasonic pulse and measures the time taken for the echo to return from an object. This time-of-flight data is processed to calculate the distance with high resolution. The sensor’s integrated signal conditioning circuitry provides a clean, digital-compatible pulse output for straightforward interfacing.
Engineered for robust performance across an operating temperature range of -40°C to +85°C, this module is suitable for use in varied environmental conditions. Its low power consumption and fast response time make it an efficient choice for battery-powered or continuous monitoring applications in robotics, industrial automation, and IoT sensing nodes.
