2 Pcs Ultrasonic Distance Sensor for Arduino High Precision Waterproof Low Power Consumption Integrated Ultrasonic Sensor Module for Distance Measurement Obstacle Avoidance Industrial Control HC-SR04T

Arrived as shown, arrived on time, perfect condition. Great buying experience. Would buy again. Thanks

Got these for a water level circuit at an off grid location and these seem to fit the bill. Used these with a ESP32 board and being a total novice managed to get the circuit working just like I wanted. Did fry one sensor, accidentally connected power to one of the signal pins, that didn't go well, who knew, so don't do that LOL.

I used this ultrasonic distance sensor for a project involving distance measurement and obstacle detection. It worked great and provided accurate readings even outside. The waterproof feature was especially useful since I needed it for an automotive project where moisture was a concern. It worked well with Arduino; however, I wish that the board had more than one sensor input. Just wishful thinking! LOL! The low power consumption made it ideal for my needs. For me, it worked well for distance measurement and obstacle avoidance, and I'm very satisfied with it.

These ultrasonic distance sensor modules are a great choice for projects involving distance measurement and obstacle avoidance. The fact that they are waterproof and have low-power consumption design makes them suitable for a variety of applications, both indoor and outdoor. I've found them to be reliable and accurate in their measurements, providing consistent performance. They're easy to integrate with Arduino and other microcontrollers, making them a versatile tool for hobbyists and professionals alike.
