In this mode, you can interface the HC-SR04 ultrasonic ping sensor with a servo motor and the main board (Only some reward tiers include the extra servo motor PCB and servo motor kit).

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Operating at 1 sample/s, the CH-201 consumes 15 µW at a range of 1 m maximum and 27 µW at a range of 4 m maximum. At 25 samples/s, power consumption is 180 µW at 1 m and 500 µW at 4 m. Shipping now to ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...

The SM300A ultrasonic proximity sensor measures 33.0 mm x 7.62 mm x 19.05 mm and has a sensing range from 6.35 mm to 102 mm, said to be 12 times farther than similar sized sensors ...

Designed for short-range applications from 2" to 6", the RPS-400-6 ultrasonic sensor measures 0.75" x 2" x 1.5" and comes standard with integrated background suppression.

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...
