This project focuses on training a YOLOv9 model for human detection in nano-sized images. The dataset used for training contains annotated images and labels specifically designed for detecting humans ...

Full-wave rectifies mains signal and compares it to a near-ground VDC signal to produce a 'zero' crossing signaling pulse. Comparison yields a current-sinking pulse, normally high. Pin D3 receives a ...

Building an Arduino lie detector test This one caught my eye - an Arduino-based lie detector that can measure the skin's response to a question. At the heart of this project is an Arduino Nano, based ...

Arduino Nano 33 BLE Sense consists of multiple built-in sensors such as 9-axis inertial, humidity, temperature, barometric, microphone, gesture, proximity, light color and light intensity sensors. The ...

To test the device, upload the source code to the Arduino Nano using the Arduino IDE. Afterward, disconnect the Nano board from the laptop or desktop, and connect 12V to the circuit. Bring a small ...

Arduino advanced noise detection monitor. 2:23 pm April 16, 2024 By Julian Horsey. ... Powered by a combination of ESP32 and Arduino Nano BLE Sense, linked via serial communication.

My inspiration to build this device is to give an alert of a gas leak before it affects human life. Due to gas leaks and blasts, many of them lost their life. Also check our previous project based on ...
