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 ...

1 Arduino Ultrasonic Sensor (HC-SR04) 1 buzzer; Ultrasonic sensor, mounting circuit; It is a very simple circuit. On the one hand, we will have all the alerts, acoustic and visual, and on the other ...

Here is a simple 3 Ultrasonic sensor-based Human following robot using Arduino Uno code that you can use for your project. This code reads the distances from three ultrasonic sensors (‘frontDistance’, ...

Ultrasonic Module with Arduino Connection Diagram. The Following connections are made between Arduino UNO and the Sensor: Arduino Code. As discussed in the working section, we need to send 10uS pulses ...

The treat in question is detected by an SR-04 ultrasonic distance sensor connected to an Arduino Nano. All in all this was a highly successful build as far as neighborhood entertainment value goes.

The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...
