Powered by a low 5V DC supply and consuming under 2mA, these modules feature 40kHz ultrasonic transmission and TTL output signals. Complete with mounting brackets and cables, this set is engineered for easy integration into IoT, robotics, and automation projects, ensuring reliable, high-accuracy sensing with minimal power footprint. ## Description Characteristic: The HC-SR04 ultrasonic distance measuring module provides non-contact distance measuring function from 2cm to 450cm and high distance accuracy up to 3mm. Module consisting of ultrasonic transmitter, receiver and control circuit. Basic working principle: 1. Use IO mouth TRIG trigger distance, at least 10 high level US signals; 2. The module automatically sends eight 40KHz square waves and automatically detects whether a signal is returned. 3. I returned the signal, through the IO mouth, ECHO output a high level, the duration of the high level is the time of the ultrasonic wave from start to return. 4. Distance = test (high level time * speed of sound (340 m/s)) / 2; Operating voltage: DC 5V Operating current: less than 2mA Working frequency: 40Hz maximum range: 450CM Minimum range: 2 CM Measuring point: 15 degrees Input trigger signal: 10US TTL pulse Echo signal output: Output the TTL level signal, proportional to the range. Document link: https://www.adrive.com/public/rRKFHV/k000175.rar Note 1: The TRIP pin is an internal pull-up resistor of 10K. Use the IO port of the microcontroller to pull the TRIP pin low, and then give a pulse signal of more than 10us. The OUT pin is the switching output pin when this module is used as an anti-theft module. This pin is not used in the ranging module. Note 2: The module should be plugged into the circuit board first and then powered on to avoid high-level malfunction. If it occurs, it can be solved by repowering it.
