🔹 Project Details: Smart LED Distance Indicator using Ultrasonic Sensor and Arduino 📌 Introduction This project is a real-time distance indicator using an HC-SR04 ultrasonic sensor and LEDs to ...

About The Fire Alarm System Project integrates Arduino with temperature and gas sensors to identify potential fire risks. When abnormal temperature or gas levels are detected, the system activates an ...

Shifting to the new waterproof ultrasonic sensor is not a big deal, since it’s pretty easy to modify some example codes to use it. The quick road test, oh it’s a simple approach to display the ...

The traditional single sensor alarm system has been difficult to meet the requirements of multiple pollutants detection at the same time, so this research proposes a multi-sensor integrated ...

Arduino based Fire Alarm – Circuit and Working Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...

In this project, we will build Human Following Robot using Arduino and Ultrasonic Sensor. This robot can track and follow a person autonomously, making them useful in various scenarios like assistance ...

The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...
