With a low power requirement of just 5V DC and a quiescent current of under 2mA, this sensor is both efficient and effective. Its user-friendly design features an anti-reverse pin socket and a built-in MCU, eliminating the need for an external crystal oscillator, ensuring a seamless integration into your projects.

## Description

HiLetgo 5pcs HC-SR04 Ultrasonic Module Distance Sensor

## Features

- The HC-SR04 ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back.If it back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning
- HC-SR04 Test Distance : high level time velocity of sound (340M/S) /2
- HC-SR04 Power Supply : 5V DC; Quiescent Current : <2mA,; Effectual Angle: <15° ; Detection Distance : 2cm~500 cm; Resolution : 0.3 cm
- Equipped with anti-reverse pin socket – making the wiring much tighter and convenient; 4-pin anti-reverse cable also included.
- Uses the MCU STC15W104 which has a built-in clock, no need of external crystal oscillator.
