Ultrasonic Distance Sensor – Weatherproof


Availability: Low Stock - Only 2 Remaining

With a weather resistant sensor housing, this ultrasonic distance sensor is very similar to those used on modern park assist modules in cars and ideal for applications exposed to the environment. These are most accurate under 3 meters but can detect beyond 4 meters.

Ultrasonic sensors are electronic devices that utilize high-frequency sound waves to measure distance, detect objects, or monitor the level of liquids and solids. By emitting ultrasonic waves and measuring the time it takes for the sound waves to bounce back after hitting an object, these sensors calculate the distance between the sensor and the target. Ultrasonic sensors have a much longer range than most infrared sensors and do not suffer from the same issues infrared sensors have outdoors.

This specific sensor is very similar to those used on modern park assist modules in cars. The sensor portion of this module is weather resistant and has a long cable so the driver board can be mounded in a safe, dry, place. Just like an HC-SR04 Ultrasonic Distance Sensor, this module is activated with a 10µs pulse on the trigger returns an output signal proportional to the distance on the echo pin. Since these are primarily used to look for obstacles in park assist systems, they have a wider field of view. These are most accurate under 3 meters but can detect beyond 4 meters.

Distance in centimeters can be obtained by using the following formula:
echo length (µs) / 58 = distance (cm)


  • Voltage: 5V DC
