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?

  • Water Tank Level Sensor
  • Imagine getting home from work, its winter, its cold. You have a shower to warm up and half way through your shower...... your water stops. You wrap a towel around yourself, remove the shampoo from your eyes and go out into the cold to swap the tanks as the water tank you were using had run dry. This was a common occurrence in my house......... but not anymore. Now I can keep visually see the level of water in my water tanks on m...
  • Arduino Tide Gauge
  • I used an Arduino and a US-100 ultrasonic sensor to make an extremely low-cost tide gauge. This project measures the tide by sensing the distance to water using a US-100 ultrasonic sensor. The device has a 3D printed base and uses a peanut butter jar to create a waterproof housing. The 3D printed base fits atop a PVC tube which acts as a stilling well to dampen wave effects. Timestamped data is logged to a mi...

  1. Review by Campbell verified purchaser

    The sensor was easy to set up and seems to work exactly as advertised. It arrived promptly after my order was placed. Unfortunately a resource document on the use of the sensor, published on Core Electronics website contained dead links to all of the key details. (Posted on 21/01/2019)

  2. Review by Cameron verified purchaser

    We have been using these for monitoring the water level in tanks on farms and they perform really well! (Posted on 2/01/2019)

  3. Review by Nikki verified purchaser

    Used with raspberry pi zero, works fine and gives accurate measurement (Posted on 21/09/2018)

  4. Review by Chris verified purchaser

    Really like this sensor. A decent cable length and easy to install sensor. Totally compatible with the HC-SR04 if you wanted to swap it out (same pins and coding doesn't need changing). The only down side with this sensor is it appears to stop working randomly and needs to be reset to come right again. Due to my project running 24/7 I had to go back to the HC-SR04 as it seems to be more reliable, just not as good for installation and weather protection. Maybe I just have a faulty sensor with this one. Might try another one to see if it makes a difference.
