Waterproof Ultrasonic Obstacle Sensor Module with Probe

This ultrasonic sensor shares similarities with those found in vehicles but offers notable constructional benefits. The Waterproof Ultrasonic Obstacle Sensor is divided into two main components: the transducer, which acts as the sensing element, and the control board.

This module provides distance measurements between 250 mm and 4500 mm, allowing the sensing element to be placed separately from the control circuitry.

Designed for industrial use, this ultrasonic distance sensor performs well in harsh environments and is waterproof. It interfaces similarly to other low-cost ultrasonic sensors, but with enhanced durability and performance. It is compatible with Arduino, and sample codes and projects are readily available.

While many ultrasonic distance sensors are available, this Waterproof Ultrasonic Obstacle Sensor is suited for use in challenging conditions. It offers reliable performance and operates similarly to the HC-SR04 module.

To use the sensor, set the TRIG pin to 5V for at least 10 µs. The module will emit eight 40 kHz tones and detect the reflected signal. When the signal is received, a high-level signal is output through the ECHO pin. By measuring the time between sending and receiving the signal, the distance can be calculated using the formula: Distance = (Time to Receive Reflected Signal * Speed of Sound (340 m/s)) / 2.

The basic working principle:-

1. Turn on TRIG Pin to 5V for at least 10uS
2. The module will then automatically send 8 40KHz tones and automatically detect when the signal return after reflecting back from the object
3. Upon detecting the signal, a high-level signal is outputted through the IO Pin ECHO. By keeping track of the time duration between transmitting and receiving the signal, the distance can be calculated. Distance = (Time to Receive Reflected Signal * speed of sound (340M/S)) /2
