Waterproof Ultrasonic Distance Sensor with Separate Probe (20~600cm)

Most ultrasonic distance sensors aren't waterproof which can be a problem if you need your project to withstand the elements outdoors. No need to worry any more! We have developed waterproof & ultrasonic distance sensors with a waterproof sealed emitter. This sensor is suitable for outdoor applications such as car reversing sensors, security alarms, industrial inspection, etc. What will you make?
