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 ...

The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

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).

If you are just learning how to do Arduino projects or want to start, ... An ultrasonic sensor is positioned outside the box to detect the presence of a hand within a four-inch range.

The sensor package comprises an ultrasonic distance sensor, a microcontroller running Arduino firmware, a micro-SD card for datalogging, a real-time clock for timekeeping and sleep functions, and an ...

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 ...

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.
