Waterproof Ultrasonic Sensor Module

The Waterproof Ultrasonic Sensor Module is a robust and reliable solution for non-contact distance measurement in wet, dusty, or outdoor environments. Designed with a sealed, waterproof probe, this sensor is perfect for liquid level detection, tank monitoring, sewage systems, irrigation control, and harsh environmental conditions.

Unlike traditional ultrasonic modules like HC-SR04, this version is equipped with a fully enclosed sensor head, offering better durability and stability in applications exposed to moisture or dirt. It emits ultrasonic pulses and measures the time taken for the echo to return, allowing it to calculate the distance from solid or liquid surfaces with high precision.

Compatible with Arduino, ESP8266, ESP32, Raspberry Pi, and other microcontrollers, this sensor is widely used in smart agriculture, industrial automation, and IoT liquid-level monitoring systems.

Key Features:

• ✅ Waterproof & Dustproof Design
  Equipped with a sealed ultrasonic probe suitable for harsh and outdoor environments.

• ✅ Non-Contact Distance Sensing
  Measures distances without any physical contact—ideal for corrosive or hard-to-reach areas.

• ✅ Wide Sensing Range
  Typically detects objects between 20 cm to 600 cm (varies by model).

• ✅ High Accuracy & Stability
  Offers consistent and reliable performance with minimal false triggers.

• ✅ Easy to Integrate
  Compatible with standard microcontrollers; 4-pin interface (VCC, GND, TRIG, ECHO).

• ✅ Versatile Applications
  Perfect for water tank level detection, waste bin monitoring, river level tracking, and more.
