This project demonstrates how to use an ultrasonic distance sensor (JSN-SR04T) with an ESP32 to measure and display the distance on an SH1106 OLED screen using UART communication. Connect the SH1106 ...

Ultrasonic surveillance system with 1 to 3 (HC-SR04) ultrasonic distance sensors to monitor a specific area (2 - 300cm). If a change in distance is detected by one of the sensors, a 230V relay ...

ESP32 supports dual-mode Bluetooth, meaning that both Classic Bluetooth and BLE are supported by ESP32. Here, we will control General Purpose Input Output (GPIO) pins of the ESP32 board using ...

The ESP32 is a powerful, low-cost microcontroller that is widely used in the development of IoT projects.It is popular for its high processing power, low energy consumption, and built-in Wi-Fi and ...

This paper presents a sensor-based gaming system that enhances interactivity by leveraging the ESP32 microcontroller and ultrasonic sensors to enable real-time motion-based control. Traditional gaming ...

Historically, we’ve used IR and ultrasonic sensors but [Makers Mashup] decided to use an ESP32-Cam as a motion sensor in his latest animatronic creation. You can see a video of the device and ...

The system uses ultrasonic sensors and a servo to aid in obstacle detection and an ESP32-CAM to help recognize the object in front of the user. The servo is used in a sweeping motion to achieve a ...
